<t>VGA monitors are really a non-starter with the RPi.<br/> <br/> If you want a native 1366x768 resolution, you'd need to get a converter from HDMI to VGA (HDMI is basically the same as DVI but with a different connector, so a *digital* DVI->VGA converter box would work as well).<br/> <br/> Getting ...

Re: config.txt

One of the first things I'll do is hook it to a 3840x2400 display via HDMI->DVI adapter.  Ubuntu drove it out-of-the-box at full-resolution from a single-link DVI at 12Hz refresh rate.

Any bets on if it'll actually work for the RPi?

Re: LCD Touch Screen and

The RPi does have SPI and a UART, not sure if you'll need some sort of buffer chips.

Mind you that these are autonomous external devices with their own commands to control them; you won't be able to just plug them in and have your X display expand onto them.

Re: Powering peripherals?

500mA is the _minimum_ reliable current that powered USB connections need to provide.  Check any USB wall wart you've got hanging around; it probably delivers plenty above that to power the connected peripherals.
