Disc or drum

I am finally getting ready to do the front end rebuild on the 68 Barracuda. Since i'll have it apart it seems like a good time to switch to disc.

1) is it worth converting?
2) I have small bolt pattern, should I keep or switch? Switching mean $$$ for another set of old rally's, and my other sets of wheels?
3) any recommendations on kits?

4) I am also open to thoughts on front end kits. I have some answers from a thread I did last year, but welcome all thoughts on the subject.

I want to try thinking of everything so I will not have to get into it again for a long time.
Parts; rubber or not; what to replace that may not be part of a front end kit; what to powder coat; any thoughts of what to do while its apart.

Thanks
