You can get by with some pretty basic stuff, a sharp scissors, razor knife/blades, sandpaper, some brushes, glue, thinner, masking tape, and a roller. Need a piece of chalk for marking the hood so it lines up properly.
Hit the hardware store and get a "wallpaper seam roller", it'll cost a fraction of a "regular" roller & work just as well.
A pair of pliers might be in order to help strip off some of the old seam tape, and a mandrel of some type. 2 litre soda bottles work remarkably well for replacing cuffs.
I did a slide show on cuff replacement, you can download it from:

Neck seal & hoods use the same gluing & surface prep techniques as cuffs, but it's going to be "experiment time" to nail down a proper form or mandrel for doing them. Depending on the type of suit, a 5 gallon bucket may work, tho some folks can work them flat.
Don't skimp on the surface prep, it's critical in getting a secure glue job.
Zippers can be done 1 of 2 ways; strip out the old zipper, or just cut out the teeth & stops on the old one.
good luck & have fun.
