Janet, those colors are great, I think the red accents will be easy, but don't try to paint any walls red (well only one accent wall if you have to) its so hard to paint red evenly. I tried it once and it was a huge pain.
Ikea is great, I like the one in Woodbridge better than College Park, they have more in stock since its not as busy and of course they don't cater mostly to college students.
When my mom moved into her house recently she actually found a lot of great furniture at Costco. When we moved here we sold almost everything and had to start all over again and I found a lot of decor at home goods and marshalls, good deals.
Oh and the Pentagon City Macy's has a huge selection of that martha stewart stuff, its all so great, too bad I already got a bunch of "home" stuff before I saw that stuff from my registry.
let me know if you ever need a shopping buddy!
