You never answered my question in your original post about your current configuration or the 350. Do you have a carb'd engine? If so, it should have a mechanical pump, and yes, now is the time to change if for a new one; won't cost much but it's a lot easier to change when everything's apart than it is later when it starts leaking on you or otherwise craps out. If you have an in-tank pump, you don't need to change anything.
Distributor will swap. If you have '86-later carb or EFI, you should get a 350 knock sensor & module, although you can probably live with the 305 piece.

Grab a v8 tank from a junkyard and usually you won't get smacked with the fuel pump price or take it out and hide it 
You definatly need the connecting lines and have to upgrade to high pressure line.

You're also going to need the computer and wiring cause these cost $.
Other cheap options are to get the motor, get sensors out of a junkyard (pocket stuffers) and a computer...
