Actually, I don't think this is a problem anymore; it used to be, but
I think most BIOSes are fine now and GRUB may even be able to work
around that where there is a BIOS limitation. With the first 10 GB of
his disk being Windows already, there will be no way for him to have
the kernel be in the first 1024 cylinders. Anyway, that's not a
problem.

I like to have 1 GB, just to have a nice big space that I know has no
chance of filling up. If you are tight on space, then 512 MB is
probably fine.

This is a must. It makes upgrades and reinstalls much less painful.
You will always be able to keep you data no matter what you do to the
rest of the system.

This is good, but I'd add about 1-2 GB /home parition, and maybe
shrink /boot to 100 MB or just include it in /. There is no reason
(that I can think of) to have 200 MB worth of kernels laying around,
unless maybe you are testing several configs. On one machine with 4
kernels installed presently, I'm using 18 MB of space on /boot.
1-2 GB on /home leaves you about 5-7 GB on / (I figure your "20 GB"
drive is probably more like 17-18 GB, leaving 7-8 GB for Linux), which
should be good for a decent size install.
I recently setup and old machine for a web server with a 10 GB disk.
I decided to try out LVM and created has the seperated partitions
because it is a server. It's about full by today's standards, but I
have a 1.5 GB /http that is barely used (so far) and I also left some
unallocated space in case I wanted/needed to grow an LVM. So it is
possible : ).

Different people have different tastes, but I'd say go with a small
number of partitions and you will be fine. If you split it up into
too many partitions, chances are you will end up with too much in one
place and too little in another.
Have fun learning Linux.
