That's pretty generous.  You probably don't need that much.  Really 10G is a lot.

How much RAM do you have?  Generally you want swap to be twice RAM, but that 
falls apart when you have a lot of RAM.  I have 2G RAM and 2G swap, but my swap 
generally is 100% free.

Way too much.

Again way too much.

What are you using /common for? I'd just create /home/common and set the 
permissions however you need them.  OTOH, it is your system, so its not that 
unreasonable to put something else in /.  Just not the usual practice.

Actually, I'd probably set the whole disk up using logical volume management and 
leave disk space I didn't need in the near future as empty.  Then you can just 
grow the partitions according to need.

Sure.  Just fdisk and delete the partitions and recreate them to the size you 
want.  Or you can set up logical volumes there too.

Yes, that is easy.
