I have a Fluval 405 on my 48 gallon and love it. A 205 would be perfect for your tank. There's lots of different options for what media you run, the ceramic bio-media is fantastic and the thing is basically silent.
With enough digging on the internet you may be able to find a steal on one. I got my 405 for around $130 with free shipping on ebay...they retail for like $260 at my lfs
Personally I don't see a need for a UV
filter (inline UV
's tend to not be very effective from what I've read) and as long as you maintain a clean and healthy tank it shouldn't be necessary.
