There's a TON of different EQ pedals out there that you could try. The main question is, do you want graphic, parametirc, or both? Also, why do you need an EQ? Amp EQ not cutting it, or you want to cop certain tones?
If you're looking for a compressor, look no further than
http://www.ovnilab.com/
there are major major major reviews of compressors on bass done by fellow forumite Bongomania.
As far as effects that Wolstenholme uses... I am 100% sure that if you even just looked back 1-2 pages there would be at
minimum 5 threads about just what you have asked.
As far as bass fuzz, if you're looking for a muff type fuzz unit for bass, look up the Wren and Cuff Pickle Pie B, the Way Huge Swollen Pickle, the Blackout Effectors Musket, the Earthbound Audio Supercollider (you can only find em used nowadays), or a black russian muff on the used market. If you're looking for something other than a muff, take a look at
http://bassfuzz.com/
which has major major major reviews of various bass fuzzes and other things done by one of the forum moderators, Grygrx.
