My car had the same issues too, but I replaced the transmission fluid (with regular dino oil) and it seemed to help. It still grinds a bit when it's cold, but if you're careful with it for the first few minutes, (slower shifts, lower revs, etc) then it should engage fine until it warms up....YMMV..IMHO...
How long can you drive on bad syncros? Tough one to answer....depends on your driving. If you're hard on the transmission, not long. If you take care of it, then sky's the limit. (again: YMMV....)
