For Tahoe, you may also want to check out the TRT (Tahoe Rim Trail) which uses part of the PCT on it's course. I did the entire 165 miles a couple of years ago (in sections) and it is beautiful. Each section is unique, my favorites being the east side (some smaller legs, around 12 miles if you set up a shuttle) w/ great views across the lake. The 32 mile section that includes the PCT is a great backpack thru Desolation wilderness, but not really many views of Lake Tahoe, but you have many other alpine lakes to choose from, so you won't miss much.
Another option if you want a short, quick hike is look at Emerald Bay and the Vikingsholm trail. It's steep down and up, but short, and beautiful. My page has a picture of me on crutches at the top of that hike.
