You are starting wrong. Real programmers won´t use Windows even at gunpoint. Windows is good mostly for gaming. For Photoshop, there is OSX, which is a full fledged Unix. For people who use Real Operating Systems, a bunch of Lisp environments (including Emacs + Slime) are just an apt-get away. Weblocks seems to be a nice web framework. As for the third hit on Google (Kanamit), it was a prank.
As for #2, http://www.lispworks.com/documentation/HyperSpec/Front/index... seems to be a good start
As for #3, that one got me. I am mostly a Python/Plone guy learning Django, but I am sure plenty was developed in the last couple decades for Lisp. Since it takes a smart person to do it, you shouldn't find lots of lousy stuff.
