I am designing the SD card controller IC.
which type pad should I select to connect with SD card?
SD card's IO is push pull circuit.
How can I select controller IC pad's drive capacity? About how many ma pad should I select?

You can interface SD card with PIC controller on SPI line.
And dont be lazy, search for it,
How can you directly ask for code.??
After using SPI communication, if you have any problem then post a topic.

Who is the manufacture of the SD card? What is the capacity, 2GB, 4GB, etc. Is it a straight SD or SDHC?
The reason I ask it that the protocols are slightly different.
I'll look your code over and see if anything jumps out at me. It's been a while since I wrote these routines from scratch.

For the project I'm working on we have a student sprite that can wonder through 5 rooms and is controlled with the Keys.
Oh, we're also trying to make the music be triggered based of the x and y position of the sprite (which will be tricky in itself)
Can you give some details about the "sprite"?

Sd card has 2 types of protocols. The first is SPI and the other i SD. The SPI protocol is very common and easy to implement. SD protocol is more complex and secure. I read somewhere that the SD protocol is faster than the SPI, I don't know if that is true.
