Pete already done an excellent job answering most of your questions so there is very little I could add except:

When doing about 50'ish trimix dives a year, it boils down to about US$10 per trimix dive for me NOT counting the boat fee, just the cost of running the Rebreather unit (i.e. gas, sorb, sensor, batteries, etc).
Amount of weight depends on the actual unit used. Certain units are more buoyant than other, but in general very similar to the amount needed for OC diving once you are used to the unit. Same as OW class, in the beginnin you will tend to be more overweighted to compensate for lack of refined buoyancy skills.
It is too easy and very tempting to go deeper (i.e. trimix diving) on a CCR too early since there is no gas issue WHEN everything goes fine. When they don't, it is harder to realize without having the experience to detect and deal with those problems. Take your time and develop the experience level and skills needed.

Dive safe!
