1. by all means check the rod, as if it is bent you will have clutch problems
2. zerk? I assume you mean nipple? whereabout is it?
3. do the forks yourself, 20w oil use an impact driver to take off the lower screws (1 either side) and pump forks till all the oil is expelled. fill up with correct amount. I'd let the shop do the master cylinder, although I've seem a couple on NOS ebay which would be cheaper!!
