Kinda depends on your budget.
Any wah will do. like a crybaby or a cheaper guitar wah, or maybe a ibanez weeping demon. Cliff used a Morley. If you got more money to spend the Wilson wah's gets some praise around here. Also worth of note is RMC. My guitar friend has one of those, and they are supposed to be real fuzz-friendly. Personally I use a envelope/low-pass filter with an expression pedal.
Fuzz.. well, really anything will do here too. A muff maybe.. Lots of good clones out there. I can most definetly recommend a Supercollider. Also check out The Grey Stache, the Bluebeard and the Musket fuzz.
The Oxfuzz Bass also deserves a mentioning. Also I think a suitable Tone Bender clone wouldn't do you wrong.
Do some research and hunt for clips if you don't have the opportunity to try some out.
Chorus. I don't have too much experience with this one. I have EHX Stereo Clone Theory coming in. It is cheap and supposed to have nice tone, but is abit noisy. The DLS Ultra Chorus II is said to be great, but more expensive. I think the Analogman Chorus /w Deep switch is one of the more popular ones around here. I tried a EBS UniChorus once and thought it sounded good..
