My advice.
1) If the game is being raked, don't go back.
I don't mind giving people who run and deal home games tips - but if they're raking from the pot, that's illegal, and there's no guarantee that they're not taking way more than their fair share from the pot. You really can't get ahead in that game anyway, so your best bet is not to play.
2) Establish a virtual bankroll - then make it a real bankroll.
You have $200 a week you can lose on poker. Make a spreadsheet in Google Docs or whatever you're comfortable with. Decide how much you can flush down the toilet in, say, a three month period. $200 * 12 = 2400. That's your virtual bankroll. (You really should have 4000 for this game, but you're not a pro, you're an amateur, so it's okay to be a little light). Keep track of your buyins and cashouts (wins, losses). Eventually try to replace your "virtual" bankroll with your *real* winnings, if you're a profitable player -- consider the $2400 a "loan from yourself to yourself" that you have to pay back.
I've created a Google Docs spreadsheet for you (or anyone else) to copy at this link:

It won't tell you what to do, but it will give you an idea of how much you're winning, losing, whether you should stay in games or not, etc. Long story short, you can't be sure of your decisions if you don't have the data.
3) Tighten up, wait for premiums, raise bigger, don't bluff. ABC poker.
