My first bottled batch was fully carbonated in under a week, and ended up being somewhat overcarbonated not long afterward. My second batch was fully carbonated in about a week and didn't end up overcarbed. On my third batch (an amber ale), I let it sit in the secondary for a week and a half, and it came out VERY clear - ie - not much suspended yeast to carbonate it. I tried it after one week, expecting full carbonation like my first two batches, and it was almost flat (a slight hiss and a hint of bubbles, but not much more), so I was a bit worried - sounds just like your situation. But around the two-week mark, it was perfectly carbonated.
I say RDWHAHB - Since you let it clear quite a bit in secondary, it sounds perfectly normal for carbonation to be incomplete in just one week, and since you are at least getting some signs of carbonation, it sounds like it's still on track.
