When I first install vista RC1 I get many options for setting my screen
resolution. However, after I set the resolution my options go from many to
only two options. (800X 600 and 1024X768) Any thoughts?

The amount of Video RAM determines the resolution size your Display can use.
I took this from the product guide:

Graphics memory bandwidth, as assessed by Windows Vista's built in system
assessment too WinSAT.exe, of at least 1,800MB/s at following resolution:

Desktop PC: at a monitor resolution of 1,310,720 pixels (equivalent to 1280
x 1024)

Appropriate graphics memory for specified monitor resolutions expressed as
total pixels (x dimension multiplied by Y dimension):

64 MB of graphics memory to support a single monitor at resolution of 1,310,
720 (equivalent to 1280 x 1024) or less.

128 MB of graphics memory to support a single monitor at resolutions higher
than 1,310, 720 pixels and less than or equal to 2,304,000 pixels
(equivalent to 1920 x 1200)

256 MB of graphics memory to support a single monitor at resolutions higher
than 2,304,000 pixels.

To achieve the memory requirements outlined above on systems with Unified
Memory Architectures (UMA), also called shared memory or integrated
chipsets, 1 GB of dual channel configured system meory (RAM) is required.
The system needs to have at least 512 MB of RAM available for general system
activities after graphics processing.
 
Here was my problem in similar situation:

My TV ("second monitor") was hooked up, so it defaulted to the resolutions
supported by the TV. To fix this, I had to go to display settings, select
second monitor, click "expand desktop to this monitor", click apply, then
unclick expand desktop onto this monitor, then I got my standard modes back.

I think initially it uses all displays as a unified display, because it
doesn't know which you are using. You have to tell it which to use.
