Finally managed to get Arch running on my Macbook Pro, very few issues, but the only things that bother me is the LCD Backlight is always on max brightness, and what bothers me more is the Keyboard LEDs always on max. Is there any way to set the last values on reboot? Or even change the default?

I have no MacBook so this answer might be wrong.
Usually, there are files that you can echo some value into to set the display or keyboard brightness. I found this link: http://blog.fejes.ca/?p=510
The commands are:
# echo YOUR_BRIGHTNESS > /sys/class/leds/smc::kbd_backlight/brightnes
# echo YOUR_BRIGHTNESS > /sys/devices/virtual/backlight/mbp_backlight/brightness
Possible brightness values seem to be 0-255.
To set this at boot, try to put both commands in /etc/rc.local.
Alternatively, you could use laptop-mode (https://wiki.archlinux.org/index.php/Laptop_Mode_Tools) and probably set these values via /etc/laptop-mode/conf.d/lcd-brightness.conf.

I have a Macbook Pro 7,1.
You should try installing pommed (http://aur.archlinux.org/packages.php?ID=14833) and nvidia-bl (http://aur.archlinux.org/packages.php?ID=25467). That should let you control the screen and keyboard brightness with the function keys.

That wasn't the issue, I could control it fine, but whenever the display would dim from not using it (Gnome3) when I moved the mouse, the screen would go back to max brightness and the keyboard would be at medium.

I'd say the same thing as Markus00000. A few lines of bash would solve this.

So, what i have done was put
echo 0 > /sys/class/leds/smc::kbd_backlight/brightnes
into my rc.local file, and it's still on at boot.
EDIT: Alternatively, if anyone knows how to entirely disable the keyboard backlight, that would be fine too, it's a useless feature for me really.

this is missing an 's' at the end (which you would have seen if you tried the command manually first). Have you checked if '/sys/devices/virtual/backlight/mbp_backlight/brightness' exists? can you do a 'sudo echo 50 > /sys/devices/virtual/backlight/mbp_backlight/brightness' ? I don't want to sound rude but on this forum you're expected to do a little work yourself.
