If Scheme implementations count as a tool, then (Tigger voice) comparing implementations by the dozen is what Schemers do best!
I'm partial to Guile and Gambit. Guile because it has comprehensive POSIX support and is an awesome glue language. Gambit because it has a compiler that emits fast code and an easy C FFI.
I prefer Emacs to all other text editors, but I frequently use whatever vi version is hanging around for quick edits and config changes.
VCS, the order goes Darcs, git mercurial, the rest.
Image editors, I dunno. GIMP, Krita, and GrafX2 I use at different times for different things.
