I was thinking about heading up to the Tahoe Vicinity, arriving Thursday leaving Monday or Tuesday. It will be my first time up there. Will I have a hard time finding a campsite? What should I expect as far as crowds go? Specifically on Lover's Leap...
Heading there on a Thursday you shouldn't have an issue with a campsite. They will all probably fill up by Friday evening though. If, for whatever reason they are full there are plenty of options for dirtbagging and free camping around that area.
I wouldn't expect to be the only one there. If you are dead set on routes to climb you will probably wait to get on at least one. If you can be flexible there are a ton of climbs there to choose from, lowering your chance of waiting in line.
