How to i/f DongleBasic to 4.3" LCD driver

Now that I have gotten the wiring proper on the Prop ProtoBoard to the 4.3" LCD, used the PSB Graphics and Paint demos of Rayman to prove things are working right, now I'd like to try DongleBasic and a SD card.
I've not tried to do so yet, because there are several other things involved, but do I need to do more than substitute PSB_LcdDriver for BB_FullDuplexSerial? I've yet to used the DongleBasic, so that will be a different experience.
I also will need to add the keyboard wiring and SD card wiring on the pcb and the drivers for them. Oops, I now see the 'input' to FDS would have been the equivalent of the keyboard i/f. More work here it appears.
I'm wondering if there is RAM space for all the objects needed. How does one interpret the Stack/Free RAM space? I do recall discussions before determining that isn't straightforward. I'd hope that double-buffering the LCD display RAM space isn't required, so as to conserve on RAM. I suppose that will be a 'try it to find out' task also.
Any clues on these questions are appreciated. I actually hadn't planned to use any Basic, but a suggestion that DongleBasic included an SD card sounded like one way to get started with SD card use. Might there be a better object than DongleBasic for this? (Yeah, more questions!)
