Hey, nice. Sleater Kinney joined in on "Rockin' in the Free World" at the Pearl Jam concert I went to last year. I haven't listened to a ton of their music, but I agree that Carrie Brownstein is great, so I should probably check them out.
That's cool, man. If you're looking for a fun and motivating way to get some writing in every day, check out 750words.com. I wrote there for a long long time. Unfortunately it's a service you have to pay a bit for now, but I believe there's a free trial, so I'd recommend trying it out. You can earn badges for your writing, which are an achievement or trophy equivalent, and that's fun if you're into such things. It will also track lots of other stats about your mood and most used words for each day. It provides good incentive to just write, about absolutely anything, every single day.
