Yeah the 2.0 sump will work and be better than the 1.8 silvertop sump. I run the silvertop on mine, but if i done it again or could be bothered i would go for the blacktop sump. You may just need to extend the downpipe slightly, or even have it done by an exhaust place to make sure it doesnt sit too low and catch on everything.
You will need to make a small bracket to bolt the driveshaft bearing support to the back of the engine. (And yes the bearing sits inside the bracket). Your driveshafts will already have this type of setup!
Depending on your skill level, just make your own engine mount. Its not too tough.
I use an HO inlet, but you can use various. I lot of people use the standard blacktop ones now, or just use a SO one. I wouldnt bother with the rover inlets. Have seen a few interesting builds using nissan pulsar inlets.... theyre plenum manifolds with ITBs inside.
Are you going the turbo route? Ive got a mk4 fiesta with 300bhp zetec turbo.
