Dandu, Shadowdancer is fine for 2 levels. It only sucks after that. On a related note Borthos, I know you said you like the shadow jumping, but it sucks. Don't get it. It's too limited in use and requires you to pick up a shadow companion that's basically a ticking time bomb for xp loss.
For abilities, I would do Str 14 Dex 18 Con 14 Int 16 Wis 14 Cha 12. Int is 16 because skill points aren't retroactive. Dex is 18 because...you're a rogue. If you want to be a burly rogue, I suppose you could make str and dex 16 and still have two points left over. Probably best then to drop cha to 10 and raise Con to 16.
I recommend considering a 2 level dip in Barbarian, Barb dips were always one of my favorite things to do as a core rogue. Fast movement is great, you get uncanny dodge (or improved) early (if you plan to reach rogue 8 you'll get cheated out of a class feature in the end, though), proficiencies, beefy d12 HD, and once/day you can gain significant combat prowess.
If you want to use a 2H weapon and not be small, I still would avoid human. There's not many good feats in core, it may help early on, but after a while it'll have been a waste. Further, as a rule, I always try to pick a rogue race with some sort of enhanced vision. At the least low-light, ideally darkvision. It's hard to be sneaky when you need to carry a torch...
Dwarf, even with the speed hit, is just crazy awesome with all its racial features. Wood Elf will give you +2 Str and Dex for -2 Con and Int, an overall decent trade. I would go with one of these. Orc (not half-orc) is alright just for the massive str alone, and it has darkvision.
Feats you want: Dodge, Mobility, Spring Attack, Improved Initiative. That's basically it. Core sucks like that. You can go Combat Relfexes (I suppose you need it for Shadowdancer anyway), Expertise, Improved Trip if you want, but then you should REALLY be using a spiked chain. Or at least a guisarme.
Other feats: Power Attack if your BAB is alright. Blind-Fight is never awful, but it won't help you get sneak attack when someone's concealed, which kinda bites. There's honestly not much else of benefit to you for feats.
For build, start in Rogue 1. Fit in Barb 2 and Fighter 1 or 2 (only if you need it for feats), otherwise straight rogue until your 2 levels in shadowdancer. See if your DM will allow shadowdancer's evasion stack with yours for Improved Evasion.
