First, as stated above, get yourself a hydrometer. This is a bit hypocritical on my part, as I don't use it all the time, but it's like wrenching on a vehicle in the garage. You can't beat having the right tool for the job. It sounds as though you may still have some fermentation taking place, so you would be well served to let the beer stay in the fermenter. As for dry hopping, I read (on here) a while back that gently rocking the secondary once every day will settle the particles out. I've done this twice with pellets and it worked beautifully. Can't speak on whole hops, but it works for the pellets. Before I used this technique I just siphoned under the green top and dealt with what came through as best I could. It still made beer, and damn good beer at that!!
If your airlock is still bubbling, use the next week to get a hydrometer, gently rock the fermenter every day, and relax in the knowledge that you're going to make some outstanding beer. The "grassy" thing has not been a problem with my palate thus far, and I loves me some home-made IPA
