Being quite a big fan of Fender Jaguars, here are some of the links I've collected so far while researching before I got my Jag... hope it helps
1) The Higher Evolution of Off-set waist guitars:
(Really good site. Includes setup, reviews, etc. You'll find the interactive Flash on how the switches in Jag work here too)

2) Mel's Jaguar and Jazzmaster page:
(another good Jaguar and Jazzmaster page)
http://www.jagandjazz.com/
3) Fenderjaguar.net
(good setup tips and gallery)

4) Jag-stang.com
(a cool site on Mustangs, Jags, Jag-stangs and Jazzmasters)
http://www.jag-stang.com/
5) Fender Mustang web
(site dedicated to Mustangs)

6) Fender Forum (Jag and Jazzmaster section)

BTW, not sure about Mustangs, but Jaguars are hard-to-please creatures and they're not meant for everyone. People either hate it or love it...hahah...almost all of them require set-up and have many issues that people find annoying...like noisy bridges, strings popping out of the saddles, loose saddle screws, puzzled over how to use trem-lock, switches, etc...and all these require some form of attention in one way or another. But once you've got them figured out, it's pure joy (okay lah...in my opinion cos it's subjective)
The short-scale neck on Jags are really nice to play with (esp. for my small hands) and body contour feels better than a Strat (again, it's my preference over my strat). Japanese Jaguars have pickups which tend to feedback quite easily but still sound nice nevertheless...US. reissue ones are fuller in sound and better protected against feedback (due to wax-dipping). I could go on and on, but it's better if you do the research yourself and savour all that info and graphic overload *lol*
Alternatively, you can check out other Fender 'hybrids' as suggested by Subversion as they can be the one you're really looking for
Enjoy!
