Personally I come from Common Lisp world, so can't say much about other Lisps tooling. In CL I just mainly use couple of different implementations, whatever might suit for the job best. Mainly SBCL with some CCL and ECL thrown in there. Library-wise not much out of the ordinary. Either just built-in tools or maybe some usage of the most common libraries like alexandria (basic utils), cl-ppcre (regex), uiop (OS stuff), usocket (sockets), bordeaux-threads (threads), Closer-MOP (meta-object protocol) and some web tools like Clack with Hunchentoot or Woo etc. So nothing really out of the ordinary in CL.
The language spec of Common Lisp is pretty large (not necessarily a good thing) so the built-in libraries offer a lot so you don't necessarily need much third-party libraries. Issue with this along side the size of the spec is the fact that the spec is old, so it's missing some crucial stuff from it like threading etc. in which these third party libraries comes in handy.
