Usually starting from UTG would be 55+. AQ+, then the closer you move to the button, the more hands you incorporate into your starting hand. From MP I would start adding in suited connectors and HJ would be suited 1 and 2 gappers. If blinds are weak, then I would play almost any two cards from the button (this would be with no other action in front of you).
Also, my range depends on the table as well. if there are a lot of loose players, then I will play a tighter hand range. If the table is tight, then I loosen up my ranges.
I think someone else said it best, that any hand is technically playable. To get ranges though you have to take a lot of things into consideration like stack size, position, who else is playing at the table, etc. The nice thing is that there are hundreds of such resources both free and paid for around the web and CC itself. I would check out the poker strategy section in CC first as they have some beginner ranges you can start with and then build upon as you advance. Best of luck!
Ranges morph by many variables, position is king but other things fall in to play that will tighten or open your range considerably. I would suggest to download Equilab from PokerStrategy and some range charts and then work your way from the basics on up.
