DO NOT GET a solar filter that goes on your eyepiece. The only solar filters to use go over the front of your scope otherwise all the energy is concentrated in the filter and they can break. Tread carefully with solar observing.
In the beginning of your observing career I would say to only get a moon filter (preferably a variable polarising one). This will make observing the gibbous moon much more pleasant.
As for the coloured filters, UHC and OIII, I would hang off for a while and get to know what you like looking at and take it slowly, then you don't end up with expensive paperweights.
