2.8"TFT V1.0 & SD V1.0 with RS jpeg on Mega dtk help!

My name is John,

Im fairly new to the Arduino platform but I've been programing for decades. This one has me stumped due to vague documentaion and libraries that dont work for me. First I cant find clear documentation on any of the products, for example. What does the SD card and the TFT use for Select Pin? I'm thinking they both use pin 10 based on the Uno's pin config. But I can't confirm that. First here is what I'm working with.

I am using the Arduino Mega DTK, SD card v3.1, 2.8" TFT v1.0, and radio shack camera cat. 2760248. I have the Mega on the bottom, then pins 10,11,12,13 of the SD card shield bent inward and jumpered with these pins SD-pin10 to Mega pin53 and cut trace on bottom of SD card shield to seperate pin10 of the TFT so it can run to A4 on the same shield. So Sd Select on pin53 and TFT Select on pin A4 and then the rest of the SPI pins on the Mega,51,50,52. The jpeg camera I have hooked to mega 16,17.
So From Bottom to top it's Mega, modified and pin diverted SD Shield, then TFT Screen on top.

can anyone help me?

thanks
