A good way to keep the color light and the flavor from tasting like "cooked extract", is by adding the majority of the extract at flame out.
There are several advantages to this- one is reducing maillard reactions (similar to caramelization flavors). Another is that you have more room in your pot for a bigger volume boil if you don't have 6 pounds of extract in there! That's important for people brewing on a stove top with a partial boil. it also keeps the color light.
As far as the boil time, that's strictly for hops utilization and has nothing to do with the extract. The thing is, a 30 minute boil of hops will taste a bit different than a 60 minute boil will. It will change the bittering character a bit, as well as require more hops. But you may find that you prefer it, so it is worth a try!
