Why don't you put a little + next to the ones with the dropdown?
I think I wouldn't worry TOO much about that, because the page is well optimized. The images aren't horrendous, and it's pretty well organized. I cleared my cache and realoaded the page three or four times with an average load time of about 4 seconds. I even tuned down my download speed a little and it didn't even hit 10 secs. If a visitor were to leave the site within 10 seconds of first arriving because they didn't think there was anywhere else to go... They are definitely impatient, and much quicker to glance over ALL the content than I am.
