Minecart Storage Help

So, i have been trying for a while to make a simple minecart storage system like this one and i can't figure it out for the life of me. It would have 8 inputs:

stone
wood
dirt
ores
redstone
brewing
tools
misc

another thing i would want, is this:
it asks for the password, and if correct, asks for the chest wanted. you could type the chest you want, or 'list' to list them all.

So, could any computercraft/redstone geniuses tell me how to make this? Or you could make it and send the map file to me? keep the program named 'storage' if you do.

make the pass and then print the difrent choises you have then make it to output a redstone signal to a side and go to a booser track that sends the cart to you (but you can have only 6 choises exept if you have RedPower :)/>/>)
