OK, to keep some of this stuff easier to tell apart, I'm using sblocks. No secrets, just formatting.
[sblock=PLANES] There is no Sigil, but there is the Bazaar (Hinted at earlier). Anybody who's ever read the M.Y.T.H. series knows it already. For those of you who don't, it's basically a plane entirely devoted to commercialism. It's a boundless scape of tents, roads, stands, and buildings, like an alternate prime, but whose entire purpose is based on trade. Everything can be obtained.. but it all has a price. There are no free or easy portals to other planes, if you can't get in/out by yourself, or afford to hire someone to get you in/out, then that's too bad for you.
The Bazaar is; like BF mentioned RE: Sigil; basically a separate prime plane.
The other planes are all the more 'legendary/divine' type.. if you go there, be prepared to explain your presence to the powerful beings whose homes you've just entered.
There are also numerous demiplanes that are less legendary/powerful, but also much less traveled and harder to access.

[sblock=BAG OF STUFF] Basically what BF said. You load it with a pre-determined amount of 'unspecified stuff'.
Then, if you want something out of it, you pay based on which bag you have.
Bag A: deduct the cost of the item from the 'total' you had in the bag, but can only get non-magical/special items worth 100gp or less. Once purchased, the item is now in your normal inventory.
EX : You buy a Bag of stuff with 200 gp of stuff in it (total cost 210 counting the bag). Later you are adventuring and realize you need 100 feet of silk rope. You deduct 20gp (the cost of 100' of silk rope) from your bag, and add 100' of silk rope to your items list. You now have a bag with 180gp of still-unspecified stuff, and 100' of silk rope.
You cannot 're-sell' stuff to a Bag A.
You may ONLY store stuff you pulled out of the bag in the bag. It had room for it to begin with, but is too full to store anything else in.
Bag B: Same a bag A, except magical : holds more and you may pull special/expensive/magical items out, albeit at double the cost.
EX: You buy a Handy Haversack of stuff B with 10,000 GP of stuff in it. (Total cost=2,000 for haversack+10,000 'stuff' = 12,000 GP)
Later you want a wand of cure light wounds, so dig into the bag b/c you're "sure you packed one"... You pull one out and deduct (750X2) 1,500 GP, leaving you with a Haversack with 8,500 GP of stuff, and a wand of cure light wounds.
If you then wanted something more mundane, like the aforementioned rope, you would only deduct the normal cost, 20GP, leaving your bag with 8,480 GP of 'stuff'.
Bag B can store anything that was pulled from it, PLUS half of it's normal carrying capacity - It is half-filled with the 'random stuff' you filled it with at the last merchant.
In both cases (A and b) you cannot sell or resell stuff to the bag, or 'reload' how much stuff is in it without visiting a merchant.
Bag C - not really a bag, actually a portal. This one you basically treat as a portable store, with the value changes listed. (Sell stuff to the store for half, buy stuff at +10%)
SPECIAL NOTE : I see no reason/benefit to have more than one of these bags, or different types. Each one is basically just a more expensive, better version of the one beneath it...
OK, C is slightly different with the +10% thing.. it's better for buying special items, but slightly worse for buying mundane.. If you buy a C, it might be MILDLY beneficial to buy an A as well, but we're talking counting coppers at that point.. If you're gonna get a bigger bag, I'd suggest just go with one and don't bother with multiples.

[sblock=Coinage]
I usually assume for simplicity that Adventurers can be carrying whatever form/denomination/amount of coins they wish on or about their person. I'm not fond of keeping track of 'i have 258 platinum, 1003 gold, 3521 silver, and 245 copper'
[/sblock]
+1 Silk Shirt of Greater Stealth : Total cost=5,000 shirt + 1,000 Enhancement + 67,500 Greater Stealth(Silent moves/shadow) = 73,500 gp cost.
I'll even let it give the 'Circlet of Persuasion' bonuses(equivalent 4,500) since you made it look so purdy.
and you said the +1 enhancement is null vs the gtr mage armor, right?
Correct, it will NOT stack with the mage armour, however a minimum +1 enhancement is needed on any 'armour' before other things can be added (the silent moves/shadow).. basically it's a 2K tax on being allowed to put those on the item.
K, now for some specific stuff :
Binder, where's this Ring/belt of divine might from?
Also, RE: Knockback - I've read the feat now, and would be willing to allow it to you, but keep in mind that since you aren't actually large, you do not get the large size bonus to the strength check.
Also, Shock Trooper is one of the reasons I was hesitant in the first place, the ability to basically choose your opponents position on the battlefield is exceptionally powerful, especially if any of your allies have ways to capitalize on it.
Kinem - I'm ok with all those items, and yes I would allow enhancements to ground speed to stack with fel flight, since it's not a 'double land speed' like some forms of flight.
Finally, to All - I would like to re-ask BF's question about religious characters. Specifically, do any of you worship specific deities or causes, and if so, how devoutly? In a planar campaign, things like this can be very important.
Did I miss anything/one?
