Intrepid 3.2L timing belt change

I'm prepping to change the Intrepid's timing belt for the first time. A
few questions:

1. All of the timing belt kits (like NAPA NBH2522950) as well as the
separately-sold tensioners (e.g. Cloyes 95357) state that they're just
'cam tensioner assy; does not include cam tensioner hydraulic assy'.
I've looked at the diagrams in the FSM; I can't see where the tensioner
assembly can be separated from the hydraulic portion. Maybe it's an
unclear illustration. Or perhaps these kits are the tensioner pulley? At
any rate, should I go out of my way to make sure I get the hydraulic portion
of the assembly, or will the commonly available parts sold without probably do the trick?

2. I've got a choice of three brands of new replacement water pumps,
all roughly the same price. The brands are: AC-Delco, Airtex and
Eastern. Anyone have any experience with these? I'm leaning toward the
Delco make, but that's probably just because it's a familiar name.

3. Any similar brand testimonials WRT the timing belt itself? Choices
are Gates, Melling and AC-Delco. Melling's $30 more than the other
brands.

4. Anyone know offhand what size socket is needed to get the crank
pulley/dampener off? I'd like to make sure I've got the right sized
impact socket ready to go. The one I used for my 3.0L last year was
large and I needed to get it separately...

5. I'm planning on changing upper/lower rad hoses, thermostat and
gasket, water pump, timing belt, and timing belt tensioner. Anything I'm
obviously leaving out? I've got a best quote of $187.88 for these,
shipping included; sound reasonable?

Thanks,
