1. How long does the tank have to be setup for before I add fish

Run tank 24-48 hours - before you add fish
Go to Krib.com - to learn about Nitrogen Cycle. This can take 2-6 weeks.

2. What are some ideal first fish to get? i.e. ones that are hard to kill

Zebra danios - put in 2

3. Following the above, are there any fish that are totally "incompatible"
with other fish? What make good combinations?

In general - agressive fish like tiger barbs that nip other fishes fins don't
go with peaceful long finned fish. It depends what you like !

With a 20 gallon tank - you can set up a nice "community tank" - do a search on
google for "community tanks" and this will give examples of compatible fish.

Instead of cycling your tank with the zebra danios - you can get a product
called Biospira - which are the actual needed live bacteria to cycle the tank
immeadiately. Then you can add a few compatible fish right away and avoid the
2-6 week wait for the tank to cycle.

Consider adding a hang on the back power filter to your UGF. Best is Aquaclear
150 or 200.
Set up your UGF filter for reverse flow - less likely to get clogged. Ugf
filters have to be well maintained or they get clogged.
6. A friend mentioned adding white spot remedy stuff to the water....which
will make it blue. Should I add this before the fish go in or when then get
the white spot?

don't add any medicine to tank - unless fish are sick.

Good Luck and Enjoy!
