In regards to the parking lights 'read headlights', you can get them out without removing and replacing them but it can be tricky if you do not know what you're doing.

I've never needed to replace anything re: spotlights so not sure.

I get my car back tomorrow so I can do a write up for you then.

You might want to have a look on NASiOC as there are a lot of detailed DiYs' on there.
