How do I rotate a video clip, say 3 degrees? (My tripod was not level.) Are there any filters that do this?

I can't provide a solution in AVISynth, although the Rotate2 filter in VirtualDub is very good (to my knowledge... perhaps others with more experience with rotation could comment). You can select precisely the number of degrees you want to rotate it, with live preview, and it can do bilinear/bicubic sampling, which will avoid jaggy edges.

Thanks for that Actionman133. I usually only use VdubMod to test and edit my AVS script before frameserving it to either HCenc or TMPEGenc, but I've never frameserved from VdubMod itself.

I'm encoding now, and as I understand it, I'm executing a double-frameserve: Avisynth AVS (segmented AVI loading | 3D noise reduction) -> VdubMod (rotating | cropping | resizing | letterboxing) -> TMPEGenc.

Check out the WarpEnterprises' Zoom filter.
