Here's a tip to help with your temperature control when smoking on your Weber Kettle. Go get 4-6 2" binder clips, and clamp them evenly around the edge of the lid. I use 4 to start with, placed @ 12-3-6-9 position around the lid. On my kettle, I find that removing or adding one binder clip will adjust the temp 15°~25° in the direction you want. YMMV, but it is fun to play with to determine how many or how few you need to maintain temps.
Binder clips are available from most office supply stores (i.e. - Staples, Office Max), Wal-Mart, etc. Get the 2" ones, and they are usually packaged 2 or 4 in a package. Minimal investment for easy temperature regulation on your kettle. They look like this:
