Updating my E36 328i

[mike328i]

I have a few questions and wondered if anyone could help.

1. Does the m3 style steering wheel from a e46 fit the e36?

2. Does anyone know where to get bmw centre caps to fit non-stnadard alloys 18" FOX RS?

3. The lights on my central unit have stoped working any ideas + prices on fixing?

Thanks Mike
