Is my fermentation on the right track?

I upgraded my equipment and estimated my new efficiency a bit too low, so the imperial IPA that I brewed on 11/30 ended up having an O.G. of 1.10 (supposed to be 1.09). I made a two step starter with White Labs California Ale (WLP001). The first step was 2L, and the second was a bit smaller at 1.2L since the first step went overboard a bit out of the erlenmeyer flask. I oxygenated with pure O2 for a minute and a few seconds before pitching. There was a little bit of bubbling the first 18 hours, but not much action until after 24 hours. It was really active for a week, and is now slowing down. There's still a 3/4" krausen, and I took a reading of 1.033 today (12/12). I'm looking to get to at least 1.02 (hopefully). The original recipe was supposed to finish around 1.01. I also should mention that I've been rousing the carboy occasionally. Not that it matters, but here's a bubble every 10 - 15 seconds in the air lock, 6.5 gallon carboy.

Should I pitch more yeast, or wait it out? I don't like leaving it on the trub for more than 3 weeks, but I don't want to rack to secondary until it's close to what I want. I was thinking to make a new starter and rack to secondary with the new starter. Any thoughts? I have never brewed a batch higher than 1.08, so this is new for me.
