Why do you need to build the bottom end? Do you want more power than what the stock one offers? A reco'd block makes awesome power compared to your average 20-year-old thrashed one.

Why do you need a new clutch/flywheel? If they're on their way out you can replace them while the block's out, but otherwise it might just be wasted cash.

Why do you need new engine mounts? If your current ones are stuffed fair enough. You can get D series to B series mounts for like $400 from shops like Innovative or HASport.

VRS kit isn't a bad idea, but you may as well just get a new head gasket instead. A good quality VRS kit is $400-600.
