Tahoe is cool, but which resort??? Heavenly is as its name suggests, but Alpine Meadow is quaint (and quiet) but Sierra is best IMO. Look out for lift pass deals in the local ski shops too - last year was $50 - $60 a day full whack.
If you're flying to SFO you can look forward to a 4-5 hour drive and if the weather is bad you'll need chains at the top or a 4x4.
As for skiing then my advice would be that if you are going with a group of similar ability then book a group lesson together. Lessons in the morning - free time in the afternoon. If you are a 100% beginner then don't be afraid to admit it - you'll learn much more by getting the first lesson right rather than struggling above your ability. Also, drink loads of fluids and take it easy on the pop each night.
And yes, boarding is easier to get to a reasonable standard, but bl**dy hard work with lots of pain for the first few days.
Dead jealous - at least there is snow over there
