[ubuntu] Partitioning

Hiya

I wonder if someone could help me out with a rather eccentrically partitioned PC which I have just inherited.

It's running Ubuntu 12.04 and I'd like to keep that, and install Debian as a dual boot. I'd be able to do that from scratch but at the moment there's quite a few partitions to sort out and I'm rather baffled.

So, pic attached..

sda1 is where i'd like to place debian
sda2 is an extended volume featuring:
-sda7 which has ubuntu on it
-sda8 seems to be a small slice of nothing
-there's 7mb unallocated
-sda 5 is 2gb of nothing
-sda 6 is unknown
sda4 is recovery
and there's an extra 3mb unallocated

so what i'm thinking is to delete everything except sda1 and sda2, then partition sda1 to make a home, swap and root for debian, then compile the rest of the space into a storage disk for films. does that make sense? woudl the debian swap also function as swap for ubuntu? that's pretty much putting me at the edge of what i know, so i'd like some advice before i do it. other suggestions welcome.

thanks for any help!
