I'm about ready to start on a new build. I'll be using it for a lot of
video editing since that's my new play toy. I'd appreciate any input on
what's important for video editing. Memory is obvious but how important
is the video card etc.
TIA

First, find the software you plan on using, and read the "system requirements".
Some software claims to get a benefit from certain graphics cards (GPU
acceleration of playback), but based on the cards listed, it doesn't appear
to be a significant effect (a low end 7300 is in the list of supported cards).
Other software only uses the GPU as a frame buffer, and with a PCI Express x16
slot with 4GB/sec bandwidth, the slot does all the work. Virtually any
video card at the $100 level would do.
For the most part, you want a CPU. There is a benchmark here. At the top of
the chart, are $1000 class processors. The Q6600 and E6850 are more
reasonably priced ($270-$280 neighborhood), and pretty far up the list
in terms of performance.

For memory, I'd start with 2x1GB DDR2-800 CAS5. Right now, that will cost
you a grand total of $45. Since it is so cheap, if you think you really
need more (i.e. someone convinces you that 4x2GB sticks is the thing to do),
removing the $45 sticks is not going to bother you that much. Try with
the $45 solution first, and work from there. Don't be tempted by the
DDR3, because it is too expensive.
For a motherboard, pick something with four memory slots. Chances are,
that will mean a full sized ATX motherboard. Motherboards with X38 are
pretty capable (and if you get the Q6600, you may want to try overclocking
it by 25 percent). They might also make it easier to pop in a 45nm
processor (the Next Big Thing), when they start shipping at a reasonable
price.

Unless you go overboard with the video card, you won't need a monster
power supply to run it all. 500W should be plenty, if the supply is a
quality one. When your purchase list is ready, someone can work out
the power for you. (There are web sites to work out power, but I only
accept results where they "show their work". For example, Asus offers
a web page to work out system power, but all their line items are rounded
to the nearest 50W for some reason. Needless to say, that doesn't
instill confidence.)
