Two things from my experiences with a 3GM30F:
1) I was told by a Yanmar mechanic the correct way to start the engine is at full throttle and then quickly rachet back once it fires off.
2) I have never had any luck with the manual pump lift. Some people have said to manually turn the crankshaft a bit and it should engage. Never had it work for me. The only way I can bleed is to be in the engine compartment with my screwdriver ready to close the bleeding screw and have someone fire up the engine. I tuck a little paper towel around things and it really doesn't get too messy.
Don't know anything else about the other items you asked about.
