Another update: I am back to using XCode, mainly because I found Andrew Hall's excellent syntax file:

I put it in my ~/Library/Application Support/Developer/Shared/Xcode/Specifications/ folder (note: that is from my home folder - /Users/homename/Library/Etc...) and it gives me reasonable syntax and code folding. I'm running 10.6.1 and XCode 3.2 and everything is moving along nicely!
