Well, the rest of the stuff is pretty much the same, solder, becareful, get the desoldering wire cause you messed up repeat. Anyone who can read a schematic can pretty much BS their way thru it. The flash card itself though, you have it all wrong. You need to get a holder. Molex makes some, and digikey or mouser sells them as well. The holder works just like it would in a digital camera or commercial mp3 player. Press in, it locks, press it again, the card pops out. Its basicly a cage for the card.
