Power with 5v and SD card

The first thing you are going to need to do, is sort out the hardware.....
If you are connecting directly to a 5v PIC, then you will almost certainly overvoltage the device. The PIC logic outputs can deliver more current than this chip needs as a supply. When the clock and data lines go 'high', these will be pulling up to well above the chips supply voltage. This will result in the supply level for the chip rising, and possible damage. You need resistive voltage dividers on the data lines from the PIC.
Then the data output from the chip, will also need to be buffered to bring the signal 'up' to a level that the PIC can read.
The supply at the chip needs smoothing.
Do a search here for people reading/writing SD cards. This is basically the core 'chip' used in some of these, and with only small modifications, the same code (and buffering...) is needed.
