I am new to the the area and have recently took over payments for a friend on a 96 jeep grand cherokkee...4.0

I am in the west ft lauderdale (sunrise) area.. and am wondering if anyone out there know or has any recommendations on a decent mechanic.. Or how to find or spot a good one / reputable one.

I have a few nagging problems with the jeep ...

oil pressure
needs valve gaskit
muffler ( i think ) has a sound like something is leaking in engine area
AC does not work
possible fuel pump

not to sure if i should just bring it to a jeep dealer and have them put it on a computer ?

any help suggestion would be much appreciacted
I replaced all the breaks ( rotors / calipers / pads) so i think i am mechanically inclined.. just not to sure where to start
