My '86 CRX SI has the same problem. Once a year (I use my sunroof alot, even in winter) I clean it out with spray solvent then re-lube it and it works like new again! What hapens is that when the sunroof is open, you get all sorts of dirt and crap stuck in the tracks which causes the grease to get sticky. You should be able to clean it up without removing the sunroof. I usually just lube mine up with WD-40 since it seems to go longer without getting sticky. Don't use white grease, I did this once because it was what I had nearby and after about 3 weeks of gettin' dirty it just about turned into glue!

Anyway, to remove the sunroof you will need to pull out the headliner in order to gain access to all the bolts.

P.S. I know this is the wrong forum for first gen CRXs, I just happened to be brousing.
