I'd recommend getting "Harrington on Hold'em" . . . available on amazon.com.

The book is about NL tourneys, but it could really help your game.

In the meantime, here are hands I would generally raise if I was first in the pot at a 10 handed game if I was a beginner: (note that the "s" means suited, the "o" means offsuit), note that I've ranked them by hand strength

Early Position: AA, KK (these are top hands)
QQ, AK
JJ, TT, 99
AQ, AJs, KQs

Middle Position: all of the above, and:
AT-A8s, AJ-ATo, KQo, KJs, QJs
88-66

Cutoff Seat: all of the above, and:
A7-A4s, A9-A7o, KJ-K9, QT, JT,
22-55
67s, 78s, 89s, T9s, T8s, 97s

Dealer Button: all of the above, and:
A2+
K7+
Q8+
J8+

Whether you call or raise is entirely dependent upon what type of game you're playing (NL? Limit? Tourney? Ring game?).

I'm exclusively a NL tourney player, so just let me say I really don't know anything about ring games or limit (which I find to be the most confusing thing in the world - why don't you always just call given the pot odds?)

In a NL tourney, while you're still learning: If you always raised pairs TT+ and unpaired hands AQ+ in EP, I think you'd be doing fine.

The Gap Concept is important: Against a tight player, you need a better hand to call a raise with than that player needed to make his raise.

So for instance, if we are in MP with ATs, and the EP player raises, we need a better hand that the minimum raising hand in EP to call with. Thus, we need a better pair than TT or a better unpaired A than AJs. Of course, once you learn implied odds, you'll learn you can do things like call with any pair hoping to hit a set.

I hope this helps.

Well, for a n00b, I'd suggest:

Limit:
EP (UTG or UTG+1)- you should NEVER call, only raise.
AA
KK
QQ
JJ
AK
AQ

MP (next 3 spots)- never open-limp, only open raise and always raise/3-bet with the hands noted above here. Open-raise/limp/cold call 2-bets with:
TT
99
AJs
KQs

Late position- (button and cutoff)- open raise or 2-bet with all of the above. 3-bet with EP hands. cold call 2 bets or raise to 2 bets with the MP hands. Open-raise/limp/cold-call 2 bets with:
88
77
66
AJo
ATs

Open-raise/limpwith:
ATo
A9
KJ
KT
QJ
JT

Stick yourself to these and you'll make the right decisions going into the flop, but your F/T/R play will only get better with practice.

NL:
I'm guessing that you're a novice, so I'm gonna suggest only playing AA-JJ and AK in EP. (iso open raise with these, fold to any raise with these. With limpers, raise 4-5BB or whatever's a bit more than the normal raise at the table):

MP
TT
99
AQ

Late (facing a raise, fold these hands. But raise with them if there's no raise, for the 4-5BB raise or the normal isolating raise at the table):
88-22
AJ
KQ
KJ
