Sorry for the late reply!  Most of my filters are Hoya S-HMC.  They are not too expensive, and very good quality.  Since your camera has a relatively large front element, I think it is a good idea to put a filter on.
In terms of tripod.  There are so many diff. models and brands out there, the good ones are usually sold with the leg and head serperated.  Just make sure you get something with a Pan-head.  However, like someone else here suggested.  You can probably panning-handheld.
