Well, most of those applications will probably be available from pkgsrc 
and if not then some other workalike will be. And it's quite a good 
system to learn about UNIX on since it does not try to hide it's 
heritage like some Linux distros (Ubunto).

It depends a bit on your computer and internet connection, but it can 
take a up to a couple of hours on a not to old PC.

No, it's not necessary, in fact I would not do that at all if I were 
you. Using binary packages are much easier, see below for more info.

It downloads the DragonFly sourcecode to your computer so that you can 
compile it. If you have a slow connection you might want to download a 
compressed tarball of the sources instead of using cvsup. You can 
download tarballs from here: 
ftp://chlamydia.fs.ei.tum.de/pub/DragonFly/snapshots/src

Yes, the steps under Keeping up to date are good, but use the file

/usr/share/examples/cvsup/DragonFly-release1_8-supfile

or

/usr/share/examples/cvsup/DragonFly-preview-supfile

it you want preview. If you have a slow connection you might want to 
download a tarball as mentioned above.

For third party application don't follow what's written under Installing 
software, look at http://wiki.dragonflybsd.org/index.cgi/HowToPkgsrc and 
follow the steps under the section Pre-built pkgsrc packages, but use 
the addresses found on

ftp://packages.stura.uni-rostock.de/pkgsrc-current/DragonFly/RELEASE/i386/All

if a package you want can't be found there take a look in

ftp://packages.stura.uni-rostock.de/pkgsrc-current/DragonFly/RELEASE/i386/vulnerable
