Some good advice. Read a few books to get yourself "thinking" more about the game how you would react in certain spots. If you cannot afford a $30 book, then go to the bookstore and read it there.
I have been studying the game for a couple years and still have a lot to learn.
Some of my leaks in my first 10,000 hands were bluffing AK and calling turn raises with middle pair or on a draw without pot odds. I was a -1BB to -3BB at .25/.50 limit full ring.
Over the past 12,000 hands I am running 6.5BB/100 at .25/.50 full ring limit and have plugged the overcard problem as well as refined my image.

Like yourself I am new to no-limit. I am going to focus exclusively on no-limit. Here's my strategy:

1: Joined Cardrunners and am going to watch one video a day for the next month or two.

2: There are several no-limit books I own and am going to read those as well. Pro NL Hold Em, Little Green book, NLHTAP, Mathematics of Poker (about 33 percent through).

3: Play $10NL and get my bankroll up to $500 so I can play $25NL. For NL I want to have 20 buy-ins as a starting BR.

4: Post hands from my no limit sessions and get advice.

5: Transition from full ring to 6-max.

Poker is a journey. Experience is your greatest teacher. You will make good and bad decisions and learn from them. You will learn how to be selectively agressive, play tight, learn starting hand strategy, listen to your instinct, know your opponent and her tendencies and possibly her state of mind. You will find patterns to her play.
Remember to pick your spots and stack em'!
