That's a 3.2A fuse used to protect the 24vAC control circuitry.

The cap will be a round or oval silver can with 2 or 3 push on terminals on it.

No.... no part number without a unit model number. The value(s) should be stamped on the cap.

The group model was GE BWC030E.
Looks like an early 80's condenser. 30kBTU. Can't find a parts listing for it.

Don’t need a part number for the capacitor. The values should be listed on the old one.

Yes the new ones are smaller due to product improvements. Unfortunately those improvements don't necessarily mean longer life. The new caps will never last as long as your original GE ones did.

5 mfd is a typical fan value so I'd say that is the fan cap and the 7.5 goes with the compressor.
