Rebuilding the engine - what parts to use?

[Apolan]

Couple of questions..

What is the easiest way to pull out the engine? Do i need to take the trannsmisiion off first from underneeth or is there enough space in front too push the engine off the drivetrain? also can radiator stay inside or will i have to move it?

Once i have the engine outside (without oil and water in it), i will flick it upside down, put it on the cam-covers, unbolt the oilpan etc.. then disconnect the con-rods. Can i just lay them gently down on the valves or will that damage guides or whatever? The idea is to replace just the bearings without oppening the head or taking it off. Also can i re-use all of the bolts or do i need some new (for the con-rods..)?

Also i would like to inspect the oil pump, if it is working correctly. How that be done?

And the last question, do i have to short any terminals prior to checking compresion on the engine (while it is still inside the car)? I would guess not, but just to be sure.
