Quilting! Yay! There are a ton of great resources out there for you. Many local fabric stores have classes, and there are also a lot of great websites with fabulous, modern quilt designs that don't look like they came out of your grandmother's guest bedroom in 1973.
My favorite website for quilting, sewing, knitting, and other crafting is the Purl Bee. It's a group blog written by the staff of Purl Soho in NYC. They have a wonderful "modern handmade" aesthetic, but buyer beware: their store is expensive.
Denyse Schmidt has some beautiful quilt patterns that could look either traditional or very modern, depending on your fabric choice.
As far as books go: the best guide to beginning quilting that I've ever seen is the Fons and Porter Quilter's Complete Guide. It will have all the information you need about the mechanics and basics of quilting, plus some traditional quilting patterns.
For more modern quilting patterns, City Quilts is a recently published book (available from both Amazon and the SPL) with wonderful patterns designed for solid fabrics rather than prints. It also has a great section at the front about color and fabric selection.
A lot of local fabric stores offer quilting classes. I haven't taken any quilting-specific classes in Seattle, so I can't vouch for the quality of the class, but I do shop at several local stores and generally find the staff to be helpful, friendly, and knowledgeable. My favorite local shops are:
Fabric Crush in the Wallingford Center (during the summer, they have 10% off while the Farmers Market is in session on Wednesday evenings) (class schedule)
Pacific Fabrics and Crafts, with several locations in the area (class schedule)
Quiltworks NW in Bellevue - absolutely worth the trip across the bridge. Huge selection, helpful staff, wonderful store. They have an area for kids to play in one corner of the store and another area with couches and sports magazines in the other corner in case you need to bring a (well-behaved) child or adult partner with you. The website is terrible, but the store is fantastic.
There are also great online fabric stores, which are especially great if you know what you're looking for. I like quilthome.com and Whipstitch Fabrics.
If I can offer some advice myself, it would be to take a general sewing class first, before you start sewing an intricate project with lots of seams and fiddly bits. Most local fabric stores offer a basic "learn to sew" class with a project like pajama pants or a skirt that will teach you how to use a sewing machine, how to read a pattern, and the general steps to take when you're sewing something. After you're feeling more comfortable at a sewing machine, start with a lap- or crib-size quilt. The smaller size will make it faster to finish and easier to manipulate on the machine as you're sewing the blocks together.
You can choose to quilt the project yourself or have someone else quilt it for you - there are LOTS of people with longarm quilting machines in their basements who will do it for a moderate fee.
You didn't ask for it, but here's a list of useful supplies:
A rotary cutter and mat
pins and a magnetic pin cushion
extra (new) needles for the sewing machine
color-matched thread
an OmniGrid ruler (I bought mine at JoAnn's with a 40% off coupon) - I have one that's 12x12, one that's 6x24, and another that's 1x6.
a chalk marker (I prefer the Clover brand "chaco" chalk pens)
a GOOD iron and ironing board (ESSENTIAL)
thread snippers (I really like these ones made by Gingher - you can buy them with a coupon at JoAnn's, and they frequently go on sale there as well)
seam ripper
A good pair of fabric shears (never use these on paper)
Have fun! If you get stuck, take your project into a local store and ask the staff, or ask on QL! I check questions pretty regularly, and there are other sewers and crafters here to help as well.
