Don't know if your local shop will install anything that you haven't purchased from them. Obviously you'd want to get the bezel but some shops won't install (or warranty) components that weren't purchased from that shop.
Some do so you'd have to ask them.

I read on here somewhere that the rear doors are fine but the front doors are a problem. If so can they be made to fit or should I forget it. Also Is the sound improvement worth it ?
The front doors can be a problem, Randy. You don't have a lot of depth to play with. Apparently a brace for the window bracket is behind the speaker. If I remember right, 2.75" was the max depth.
Now about replacing the speakers...I have no idea what the ohm rating is for that amp. Upgrading speakers to a stock system can improve the sound but it's a bit of a crapshoot. OEM amps tend to be underpowered and may not have sufficient power to push an aftermarket set of speaker.
Having learned all that the hard way a while back, I decided I wasn't going to make that mistake again. I picked the speakers I wanted, got an amp that has more than enough power to push the speakers and only use the stock amp to provide the digital signal to the PacAudio harness adapter and on to the new JL amp.
It's not the cheapest way to go but it always works.
On to speaker sizes....dash = 3.5", front doors = you can do 5.25", 6.25" or 6.5" round spkrs with that shallow depth; rear doors = same as the fronts but I am not sure if you need a shallow mount there or not.
