No it denfinately will not
Any Chevy transmission will bolt to any Chevy motor. At least RWD. 1955 to current. A 454 should really have a 400 transmission but a 350 will work. Depending on what you are putting it in there may be an issue with the driveshaft length and the yoke that goes into the trans.
Yes.
They are under the intake manifold.
Small block and big block fuel pumps and fuel pump rods are the same on all Chevy V8's up to the mid 1980's when fuel injection and new block designs started on the market. Please note that this does not include special cam motors (roller cams, etc) that do take a different (special) rod.

If the 454 is complete with accessories such as exhaust manifolds, a/c, power steering, alternator, etc., it should be a pretty straightforward swap. Transfer the motor mounts and distributor from the 350. A new exhaust system will likely be needed.
