Help Assembling A2000

[zonaps2]

I recently got an A2000 in non working condition and a bunch of cards.
I'm only owned an A500 to this day, so I'm a noob about Amiga cards, Hard disks, etc.
It had a dead PSU that I replaced with an ATX one.
The machine boots now, but I have stripped down all the cards in their slots.
I've tested one by one each card and they all seems to work.

The cards are:
Apollo 2030 Turbo
A2630
A2091
Catweasel Z-II S-Class
Cybervision64/3D
Buddha (not sure about model, I don't have the card here with me)

Questions:

-I see that the Apollo and the A2630 are both accelerators, which one should I use?

-Is the Catweasel capable of accepting large hard disks? I mean, the machine came with a Maxtor IDE drive 170mb, I think it has some bad sectors, Can I replace it with a more modern IDE drive? Like 40Gb. I'm asking this because it's easier to find newer HDs.

-What's the use of the Cybervision card? I see that it has like a VGA connector. What type of monitor should I use for this?

I'm looking for the best configuration I could make in the Amiga with these cards.
It also has a Mini Megi chip on it.
Kickstart ROM is 3.1

Any suggestions will be appreciated!
Thanks

Thanks for the help guys!

I was able to install workbench 3.9 with the A2630 + Catweasel, I even installed a CD drive!

I have this doubt, I see that the Apollo 2030 card is faster than the A2630, but I also had some crashes and reboots with it.

Is that why you suggest the A2630 over the Apollo? Or is there something I can do to fix the crashes, etc? Maybe the card is not 100% ok?

Now, I'm gonna try to install the Cybervision64/3D card, however I dont have the scandoubler module. Will any PC monitor work? Like an LCD?
