Moving from 10.04 to 12.04

Sooner or later I will need to move to 12.04. Before I make the move I
need to decide a couple of things.
First should I upgrade or do a clean install. When I went from Karmac
to Lucid I did an upgrade. It seemed to work well and I have had no
problems, but I see a lot of people advocating a clean install. Looking
at my home directory I see it has become a jumbled mess so doing a clean
install would give me a chance to restore some order.
Thinking about doing the clean install I came up with this idea. I have
a brand new spare HD. I could put it in my case, unhook the old one and
hookup the new one. Install 12.04, get it running and install what I
need. Then hookup the old HD and copy home and what ever else I find I
need to my laptop. Hookup the new HD and copy over what I need from my
laptop. This way I have an untouched copy of 10.04 to use until I get
12.04 setup and running the way I want it. Does that make sense?
This time I want to try a separate /home partition. I'm trying to decide
how much space to give / and how much to /home. The new HD is a 1TB
one, I will probably only format about 300GB. My current HD is 500GB and
I formatted about 290GB and have 146GB free.
I googled trying trying to find some guidance on how to allocate the
available space between / and /home, but found widely varying
suggestions. I decided to look at what I was using on my setup now
$ sudo du -shc / => total 105G
$ du -shc /home => total 64G
So this tells me that if I had a separate / and /home, / would be 41G.
41GB seems large compared to sizes I saw when I doing my search and many
of those authors said they installed "tons of stuff". So is the method
I used to calculate my current / size valid?
If it was valid I am thinking of a / of ~100GB and /home of ~200GB, does
that seem OK?
