That's certainly the easiest option, and is perfectly OK as a starting
point pending you developing your own strong opinions about partitioning
practices and going around advocating them. ;->

There might be a slight performance advantage in putting the swap near
the _front_ of the drive, in such a two-partition configuration -- on
grounds of minimising average seek distance (and thus seek time). This
is one of the many, many points of dispute sysadmins happily argue
about, for hours on end.

Sure. ext3 is a fine general-purpose filesystem for Linux.

For use on Linux, it's better to create the IBM/Microsoft-style "PC"
partition table that results from using the "n" command and avoiding
creating a Sun (or BSD) disklabel.
On an earlier incarnation of linuxmafia.com, I _accidentally_ had a BSD
disklabel rather than a "PC" partition table on the 2nd hard drive for a
couple of years, because that drive had recently had FreeBSD on it.
Linux seemed to _mostly_ deal with that transparently, though there were
a few operational oddnesses that I thought _might_ have traced back to
the non-standard partition table, so I eliminated that variable when I
rebuilt the box.
