Hi, the offset looks good.
You found the 4 nuts on the torque converter converter. Remove them and push the torque converter in towards the tranny.
I have good luck applying silicone gasket maker sparingly, according to my Chilton's Manual: Put a thin line of sealer on the engine block, on the outsides of the sunken part, where the cap will sit into. Just a little line of sealer, from the very back of the block, forward just to stop at the second groove for the slinger part of the crank. Since you are working from the bottom, this will be above the oil pan rail.
I just put a small dab of sealer on each side of the bearing cap, at the edge, in line with the seal, to 1/8" away from the new seal.
Good luck
