HI! I'm getting ready to start a new tank

I've decided on FW since the SW seems way too confusing

and way too expensive

So my question(s) are...
1. what kind of cichlids can i put together?
2. what other kinds of fish can i keep with cichlids?
3. for a 150gal tank, what kind and how much equipment will i need?
4. how many fish can a 150 hold?
5. how often do you need to change the water?
6. is it best to use live plants, and do the plants require any special care?
7. how hard is it to care for a tank that size????
I know that's a lot of ?'s, but thanks for your time
