Here's a list of the things i usually do on a freshly installed netbsd system of mine
PKG_PATH="http://cdn.NetBSD.org/pub/pkgsrc/packages/$(uname -s)/$(uname -m)/$(uname -r|cut -f '1 2' -d.)/All/" export PKG_PATH
Install bash, screen, web browser etc. and some WM (I usually go for icewm or windowmaker). Note that at this point, on a completely fresh (VM) install of NetBSD i ran out of space on my 2GB / partition.
