I'm new to the game and can't enter some codes I found on this web site. any help out there?

First of all, CHEATING IS BAD !!!. But I really dont give a ■■■■ annymore, so :

1. Open the Baldur.ini file in your BG2 gamemap. find [PROGRAM OPTION] and under that line, add : Debug Mode=1
2. In the Game press [ctrl]+[space].
3. I trust you know the CLUAConsole codes. If not, you can find them on the Internet.
4. you can also press : [ctrl]+
- shift+8 = maximal Stats.
- R = heal character.
- J = teleport to where you hold your cursor .
- T = heal party.
- Y = Kill person\monster under cursor.

I agree, though. Until you have gotten your $50 worth by beating the game the first time without cheats, it's gonna ruin it. But if you are determined, Ironworks has a good cheats list, though not all-inclusive.
