Help with homebrew DS.

I am thinking of trying homebrewing but the guides on stating up are confusing. I was wondering wether to go with the supercard and superpassme setup or wther i would be better to use the new max media loader? I need more information about flashme and replacing the DS firmware? I'm sorry if I'm a hassel if someone could point me toward a more indepth FAQ that would be great. My serial number starts NU411 does that make a difference.

i use max media launcher and it works great for all homebrew and roms etc.

Is it compatible with Apple Mac computers?
