Here's some of the best (albeit heady) stuff I've ever read on the game. Not a book, just 2 somewhat lengthy articles. This guy's got a rock solid understanding of the game, IMO. The first article has 2 sections on starting hands.
As kmixer points out, aces are of critical importance, particularly if suited. As sly points out 4 low cards w/no ace are also good; if an ace plus any other low card flops, you're almost golden. Middle cards (7 - J) are kinda junk, but if all connected, or with a middle or lower gapper, playable from late position. Two connected pocket pairs are always playable, the higher the better. You development judgment w/experience, and make gametime decisions dependiing on position, action thus far, and simply how the hand works together. All 4 cards should be doing a job - unless you have something like A23x. hehehehe P.S. On the 'action thus far', if I'm in the SB or even button, and there is already a 3-bet before the cutoff, and I'm sitting there with an A28T rainbow, I will drop it like a hot potato. You will likely be quartered if you're 'lucky'.
