No problem.
"- Was the cleric a /spectral hand -conflict wound/heal a bad idea?"
It's fine. Just keep in mind the spell level limits on what you can deliver with Spectral Hand and its fragility. If you want to tank up and have spells fight for you, also look at Spiritual Weapon and summoning spells.
"Somekind of Spells to trigger Sneak attack could be new too? :b"
Sneak Attack is a great way to make an innocuous looking object into a dangerous weapon. Unfortunately, rogues already have a hitting problem with medium BAB and multiple ability dependency, so eating the penalty for improvised weapons would make it tough to have a realistic chance of hitting anything.
As for spells, there are weapon-like spells (any melee or ranged touch spell that requires a d20 attack roll), those all can apply sneak attack if they do damage. Ray of Enfeeblement, for example, inflicts a strength penalty but doesn't do damage of any sort, so sneak attack wouldn't apply with that. There are also spells to make the conditions for sneak attack possible. You could go invisible or blind the enemy (functionally about the same effect). You could grease the floor under him, since anyone w/o 5 balance ranks (99% of all people) loses dex to AC while balancing. And so forth.
"(it seems hard to make something special with 3 books though x_X')"
Yes, it is. The thing is you're basically limited to the sections of the PHB your class takes up, maybe some spells text and combat maneuver text. DMG has magic items and prestige classes and not much else of note for a PC. The way to get the most out of core is to be a druid, so you can weild the might of the monster manual for your wildshaping and animal companion; or any spellcaster in general with summoning (which druids are also good at).
"The glove seems funny, though I can't seem to find a way to abuse it..."
It's an interesting item, but I don't really spend a lot of time trying to find incredibly game breaking applications or loop-holes, so I also have no idea what crazy stuff could be done with it. Out of core, they're probably very disgusting to use with Iajutsu Focus (a samurai skill to do extra damage if you draw and strike w/ a weapon against a flotfooted enemy), if coming out of the glove counts. One potential use for the gloves that's not overpowered but also interesting is dual wielding crossbows with two gloves of storing. Normally, you need both hands to reload a crossbow, even if reloading's a free action, making it difficult to be a total badass with two of them on semi-auto.

With gloves of storing, you could free action store one, load the other, free action store that one, free action unstore and reload the first...
Oh! Glove of storing might also be useful to store an item shruken with the Shrink Item spell to set up shenanigans. I'm not well versed on Shrink Item craziness, but I'm sure you could find threads on it for ideas.
"Though the restrictions for how to activate the symbols could be hard, though Alightment; Evil? would might trigger on alot as the shield was throw'd at them (enters their square), right?"
My mental image was actually wrapping the tower shield in fine cloth and walking around like that. Then, when you encounter people you don't like, pull on some fancy rope (the thick ones with dangly threads on the end that expensive curtains sometimes have) to remove the cloth and expose the symbol.
