For someone who practices six hours a day, you should be starting to reflect and try to answer these questions by yourself, however the majority of my performance has been at parties, so I'll give a straight answer. I had a tendency to do more 'classic' street style stuff:
ACR
"Look, the card you were holding is now your other card! Now its in my/your wallet.
Various rubber band things
Some ring stuff
More simple sort of card stuff, eg, biddle etc.
OOTW was my favourite
Angle Zero is excellent for this situation, I'm going to highly recommend it now
Perhaps a nice little coins through table
That old thing where you cover a salt shaker or shot glass with a napkin, then it vanishes/goes through table
Dr. Daley's aces thing
David Blaine stuff, that isnt too heavily gimmicked.
The list goes on.
Recommended artists:
Daniel Garcia, Jay Sankey, Lennart Green, Rick Lax, Wayne Houchin, Chriss Kenner. They, among others come to mind firstly for similar styles of material that you would probably be looking for.
When seated at a table, which is obviously a necessity for some of the stuff I posted, the angles tend to be a little easier, lapping is about the most angle sensitive tabled thing in there, but you can also control that sort of thing at a table a little easier, ie, directing where you and your spectators will be sitting, the shape of the table etc.
As for standing, the "eight most powerful words" will help you, its really quite simple. With three or four people in front of you, take a step back, this will help the angles, and if they step forward to come closer to you, that should usually draw them together, also helping you. Card routines can be typically modified to become much less angle sensitive, ring stuff, particularly the Ring Thing, is pretty easily managed. A lot of rubber band stuff has quick and easy setups, that frequently can be done right in front of specs, the most dangerous one I would do is probably Missing Link, by Chris Kenner, which can still be done in an off beat.
Learn a good peek, control, force, palm and switch, and that will give you a very large amount of good card magic. Be bold in your methods and actions, not just one or the other.
With the exception of Dr. Daley's last trick, I have performed everything I listed and more to great success at many parties, you practice way more than I ever have, so I have no doubts you can be a much better magician than I, if not already.
