Okay, guys! Gather the tourist info I'm really looking forward to your answers!!!

Scott and I are planning our first trip to Scotland in 2011. (I know it's a long time from now, but in order to do it right, we have to have a lot of advance planning and saving!)
1. When is the best time to go (although we would have loved being there for the Gathering, and other than Games and Festivals, we don't generally like huge crowds.)
2. What are your top five items on your must see and/or do list?
3. What's on your "don't bother, huge waste of time/money" list?
4. Where are the best places to eat and stay and why?
5. Any further advice?
