This does not make too much sense - what is the AC load you want to control? If not bulb is it a motor? A heater? AC motors can be frequency-controlled, heaters can be TRIAC-controlled (as in the schematic you posted). For two loads, make two such circuits and control both with the same...
Bulbs are easily controlled by TRIAC-s (firing angle), so it is not such a difficult task, especially if you use some microcontroller for firing angle control.

On the same page you have posted (with datasheet) there's a link for sample C-source software

I would try it out first.
320x240lcd
You have to constantly refresh the whole screen. If your CPU is fast enough,
320x240 B/W should not be a big problem. I've done it with C8051F120 and
320x240 Colour STN running at 3BPP. Refresh consumed ca. 40MIPS, leaving
60MIPS for the application. Look for "Circuit Cellar" October...
philippine coin acceptor
Designing a RELIABLE bill/coin acceptor is not a simple task. You're dealing with the REAL MONEY, remember ! Especially as you can buy a good coin acceptor for ca. 100 EUR. Most of them can be programmed for different coins by the user. Bill acceptors start from 150 EUR...
Here are some files regarding MemoryStick interface. No software though, although it shouldn't be impossible to do it, once the protocol is known...

best compiler for the pic
I can recommend B Knudsen's ( www.bknd.com ) compiler. Interface is integrated into MPLAB and produces quite good code, even for the smallest derivates...
