Who's gonna take my thread virginity?

I have a SURE Motorsports Street Urethane RMM already installed. In about 2 weeks, I will be installing the Street Unit Passenger and Driver side motor mounts. The beater is all ready for em, battery is loosened up for easy removal to access the tranny. I need advice or a slap in the face for moving the coolant tank out of the way... The tank is secured by these clips/tabs/**** I can't seem to undo. I need to get at the passenger mount without breaking that tank.

Also when I get these mounts, how should I go about installing them?
Should I just loosen the bolts and lightly support the engine with a jacked up wooden block? Mounts in/out one at a time? I'd appreciate any advice at all.
