I think i depends on how many tables your planning on playing. If your only playing 4 tables than you can be a lot looser with your starting hand requirements because you'll have a better idea of who your playing against. I personally like to 9 table so its much better/easier/profitable to play a lot tighter.

You also need to consider the stakes that your playing at, at the 25nl, the majority of the people are complete noobs so your no really gonna want to "open up" very much. Your going to make the majority of your profit with tptk or set mining just basic strategy. Playing 87s against an early position raise with Q7s isn't really going to help you turn much of a profit.
Learn not to bluff a lot, and when you do bluff, bet big. Thats the lesson for the low limits, bigger bets work great at scaring low limit players, but remeber DO NOT do this at the higher limits. It only works with complete newbs.
So for your question in early position i only limp with any pair, occasionally AK in hopes of a reraise. And Raise with AK, AQs, AA, KK, QQ sometimes JJ sometimes limp with AQo but generally fold it.
If you want to open up your game than play short handed, then you can have fun. Don't try to have fun at full ring.
