Other than that I *think* /media is a standard Ubuntu directory, your
scheme sounds rational to me.  However, since you mention that a low
hassle reinstall is one of your goals, I'll share my approach.

Given sufficient disk space, here is how I partition my systems (yes,
I keep WinXP around for when I want to use it):

/dev/hda1	20 Gb	ntfs	/WinXP
/dev/hda2	30 Gb	fat32	/Common
/dev/hda3	 2 Gb	ext3	/boot
/dev/hda4	rest of drive in extended partition
/dev/hda5	 8 Gb	ext3	/
/dev/hda6	 4 Gb	ext3	/var
/dev/hda7	 8 Gb	ext3	alternate / for later
/dev/hda8	 4 Gb	ext3	alternate /var for later
/dev/hda9	 n Mb	swap	n=2*ram, but never more than 1536 Mb
/dev/hda10	 m Gb	ext3	/home, where m=rest of the disk

Note that /home is shared between the two Ubuntu's, but with
subdirectories for each release, such as /home/ubuntu510 for
Breezy and /home/ubuntu606 for Dapper user home directories.
This takes a little extra effort, but not much.

The alternate / and /var are used for the "next" release. So
now that Dapper is available, I have / and /var partitions
waiting for it to be installed, but it won't disturb my
Breezy system, so I don't have to be in a hurry to make
everything work today.  Also, if any of the stuff that I
use doesn't work with Dapper, I can boot into Breezy when
I need to.  Once I've made the move to Dapper and I'm no
longer using the Breezy install, I'll reformat the current
/ and /var so they'll be ready for Ubuntu 6.10.

I always have a /var partition separate from / in case something
goes wild and the log files start to grow out of control.  I
guess this is a holdover from my early FreeBSD days (FreeBSD 3.x)
when I had this happen a couple of times.

I put the swap partition physically between / and /home so that
it is, on average, likely to be near where the drive's heads
are at any random time.  It may not noticeably improve performance,
but I do it anyway.

And yes, I give a lot of space to /boot, but I keep all of
the old kernel images around - just in case.

Can't answer this since I haven't even downloaded Dapper yet...

I'd probably use /music.

Hope this helps.
