But you're unlikely to run into any serious noise issues until you start using digital FX pedals, which is where the multiple ground paths can really make a difference. Using a PSU with isolated power supplies certainly helps here, but even then, using two amps, you may then need to use a switcher with isolated outputs.
I think I will be fine...it is just so I can plug this guitar into a Bass amp and a guitar amp at the same time.

The second paragraph makes no sense to me. This is just for me to use at home mate. Thanks for the info though.
