I'd make one gear suggestion if you're taking long exposures and have a little extra cash- replace the camera body with an ETRSi. It's fairly inexpensive at KEH, and you get both bulb mode and mirror lock-up, the two things you won't find on the standard ETRS. I made this change a little while back and it's made a pretty big difference for me. Edit - I just looked at KEH and they don't have any ETRSi bodies right now except for one special edition, which carries a much heftier price tag. Keep checking with them if you're interested.
