Looks right, 900*15%discount=765gp
adding 'stealer' to my Scimitar DR 315 page 46 (whoops, this is Dragon Magazine... I can swap it for a different enchantment if you want.)
Don't have the dragons unfortunately. but if this is a +1 enchantment, then it would be in the same boat as flaming, you will need +1 first and it will add to the total enchantment for costs, so you are looking at a minimum of 6000(discounted to 5100)gp to pull it off.
Masterwork Flaming Longbow Flaming - DMG page 224 / Longbow - PH page 116
already mentioned, to find the cost you go to the list here:
http://www.d20srd.org/srd/magicItems/magicWeapons.htm and look up the combined cost. A +2 flaming, stealing weapon have a combined enchantment of +4 and cost 32000 to enchant. But the +4 only counts for making it, not using it, as such it gets +2 to hit from the +2, not +4 to hit from the +4.

I don't have a clue, sorry, I assume that it is the same on both sides, you get two of them and palm the appropriate one when throwing them. If you are catching it, then you can palm it anyway, if you aren't, then it is a big risk that it will be discovered. Probably better off getting long sleeves, calling them a
masterwork Sleight Of Hand tool, and getting +2 to all your cheats.

Don't have this either. Anytime someone uses the words "no save" I get nervous, but I really can't adjudicate balance issues.

+2 to a skill seems pretty popular for mundane gear, but don't be surprised if it is difficult to get the bonuses to stack.
Sickle, Longspear, Bladed Crossbow - PH page 116 / PH page 116 / DR349 page 22 (whoops, this is Dragon Magazine... I can swap it for a normal crossbow if you want.)
Not a clue, sorry.
Keep forgetting to check sources on Crystalkeep item lists. Let me know if anything seems 'unbalanced'.
Well, I can try again when I have more time...
