I'm not a master either, but some things that may help.

it's a ports based system. the way it works is basically that there is a list of official packages (source code) organized in folders at CRUX's servers. Running ports -u will update your local copy of those folders. using prt-get, you can pick and install packages from source, including dependencies (with prt-get depinst foo). It may be helpful to organize yourself by setting up folders for source code, building, etc. I used a guy named sudaraka's instructions for this early on, search for "sudaraka CRUX install", and remember to read the wiki, I know you said you've done this already, but do it again Read wikipedia's page on ports systems. Read about gentoo's portage system, which is very similar. You'll begin to understand it soon, it less complicated than the install imo.

>Setting up things like the Internet (Its not done the way im used to by editing something like /etc/network/interfaces )

actually I think you can do that still, but you should probably write your own init scripts to help automate this, or I guess you could use something like network manager after you get your wifi/ethernet connected. for the initscripts/an inital internet connection, there's a page on the wiki, something like autostartwifi. some helpful hints, remember you need to make sure dhcp is up for most networks, ethernet, or wifi. WPA wifi connections require wpa_supplicant, which comes included in the install, also if other network services are running from boot, you may have problems setting up network manager, don't forget to disable the others that may be running out of the box, like net (maybe lo too, can't remember).

>window manger

I usually use 2bwm, and I find it's better to install it without using prt-get, that way I can just make a local builds folder and change my config anytime I want to with no hassle. other than that, the process is pretty similar to other distros, just remember to install xorg-server, your video driver, xinit, and to make your xinitrc, and you should be fine. I think I answered the pkgutils question already, but you would go prt-get depinst git with an active internet connection after doing ports -u

keep on the course! I used crux for a while, and switched back to gentoo, but it will always have a place in my heart as the distro that taught me the most. when I started, it took me like 3 weeks to get my wifi on (I was missing firmware blobs) but I got it going eventually.

it also might help to ask on irc #nixers(irc.nixers.net) or #crux(freenode?)

EDIT:

also, man pages are your friend. most of what I outlined here is written much more eloquently in the man pages for tools like prt-get, installpkg, etc.
