You're kind of asking for a lot here but I'll throw some info/opinions out there. You might want to be a little more specific in what you are looking for since many people seem to be viewing this thread but no responding to it.
Places to Reside - depends on what type of neighborhood you want to live in; suburban, urban, semi-urban, rural, beach, inland, new, old, etc... SD has a good mix of neighborhoods for all types overall. Here is a link that describes many of them:

shopping - San Diego has a lot of malls that all have good selections. The best would be Fashion Valley, Horton Plaza, and University Town Center (UTC). The Las Americas outlet mall at the border is pretty damn cheap and has a ton of great name brand stores, it has the same stores as the Carlsbad Premium Outlets except its cheaper b/c of its predominant clientèle is from Tijuana. Downtown La Jolla is also good for expensive boutiques.
schools - generally the best schools are in suburban North County communities. This previous thread has a school performance map for SD County schools:

crime - overall SD is a very safe place, the least crime is in areas north of I-8 generally. Basically avoid the "gang injunction" areas in the neighborhoods thread listed above
Best beach in my opinion is Windansea in La Jolla.
