Installing 12.10

[George DiceGeorge]

I'm hoping to install UStudio 12.10,
on a HP Pavilion a6250.uk
it's 64 bit Intel Core 2 Quad CPU  Q6600 @ 2.40 GHz  says sysinfo 
(kentsfield)
it has Virtualization technology

I'm downloading ubuntustudio-12.10-dvd-amd64iso.
I'm going to test it on a live DVD or USB stick first.

The existing OS in Ubuntu 12.04 32bit, which has upgraded many times and 
seems to have faults.

I want a separate Home partition,
should I do this after it's installed,
or during installing?
And then copy the old Home data over?

I knew a lot about CP/M and MSDOS3.2,
but havenet enough brain left to become an expert on Linux,
I hope it will just work.
