>>1508589pic related is pretty much the bible of sierra climbing. if you want a little more detail croft's the good, the great and the awesome or supertopo's high sierra climbing are both good. mountain project has about a brazillion options, too.
if you want to overnight in the backcountry you'll need a wilderness permit. most of the east side (inyo n.f., humboldt-toiyabe n.f.) has a great online reservation system where you can see all the availability. west side (sierra n.f., yosemite, seki) are still stuck in the bronze age of email requests (they only just recently improved from snail mail or fax). each place has a list of trailhead availability on their respective websites.
also, we got a fuckload more snow this year than normal. 170+%. so if you want cushy dry california approaches it'll be late this year. if you're okay slogging through the white stuff get after it before it gets crowded.
