The best advice would be to give you no advice at all except to read the
FAQ and some of the books recommended by it, particularily Martin Moe's
books.
However, in answer to your direct questions...
No, I would not use a UGF as these trap dirt and result in high nitrate
levels. They are very difficult to maintain in the long term. RFUGF are
somewhat better but not much, and require additional aeration as the water
flowing up through the gravel is O2 deficient.
A protein skimmer is almost a necessity in a salt water tank. The only
alternative is massive water changes, which quickly ends up costing more
than the skimmer. Chemical filtration in the form of carbon or polymers is
a useful addition in fish tanks.
A 50 gallon tank is not too small for a marine system...many are smaller.
The bigger the tank is the less error prone it is however.
For a fish tank I would use a canister or power filter drawing water from a
protein skimmer, and with a biowheel or other post-filter biological
attachement. The more expensive alternative is an under-the-tank trickle
filter and sump...but a 50 gallon tank doesn't need this. For a 50 gallon
tank, an in-tank counter-current skimmer over an inlet of a fluval 403 with
a biowheel 60 on the outlet makes a good filter system. An in-tank power
head for circulation is also a good idea.
