That's your best course of action Steve - don't go changing everything at once as if one of the new parts happens to be faulty (unlikely) or another fault develops, you will be chasing your tail trying to find out why it won't start. If you've only changed one item, you can refit the original to see if that's the cause, if not then you can try other avenues of diagnosis.
That's the worst case scenario obviously, ideally you'll fit the in-tank pump, fire it up, have no leaks and no noise from the main pump after a short while. If all is good but you think the main pump is still a smidge noisy, add 2 egg-cupfuls (~50ml each) to a full tank or pro rata of ATF-U or similar synthetic ATF to the fuel tank. This will lube the pumps and also help clean the injectors and revive any rubber seals in the system.
Good luck with it and keep us posted with your progress/done report!
