Hello jbowen,

It is a good idea to keep the OS in a separate partition or disk and the
user files on another. The reason is not to keep the system virus-safe,
but when you do a reinstall or upgrade, you keep your files intact. If
you use two disks, then performance increases.

To do this, you have two option:

1- If you wan to transfer your existing system to the SSD, then you have
to boot from a live CD, create a partition on the new drive, and copy
everything friom your existing partition to the new drive with the rsync
command. I'll give you more details if this is whant you want.

2- Do a clean install, and at the partitioning stage choose "custom",
assign "/" as mount point for the SSD, and "/home" as mount point for
the other disk.

I do not understand what you mean by syncing the drives... you want to
have a working system installed on both drives?

As for what dpkg and .debs are, take a look here:

http://en.wikipedia.org/wiki/Dpkg
http://en.wikipedia.org/wiki/Deb_%28file_format%29

The add/remove application is just a front-end to apt-get, so the same
software is available in both. You can install software either way you
want, it is exactly the same. And don't worry, there's no such thing as
a registry here.
