I can try to address your points in order:
1) the only reason windows find runs fast is that it caches its results
(or you have something like FindFast running in the background).  Using
locate as Vince Hoffman recommended should produce similar results on
cygwin.
2) whereis is distributed as part of standard Linux distributions (I just
checked that there's one in Red Hat 7.3).  I'm sure a source is
obtainable, and porting it should be easy. :-)
3) for a quick and dirty replacement (searching only for binaries) try
'type -a' in bash.
