First, are you still using that plastic doo-dad that came attached to the end of the steam wand? I'm not sure how they're supposed to work, but whatever it's doing isn't good.
To get the most steam out of my Gaggia I try to start steaming a little bit before the ready light comes on. When that light comes on it means that the heating elements are off, so it's not making any new steam. If you start steaming while the light is still off, the heating elements will stay on, hopefully the whole time you're steam. I've been able to steam up a good volume of milk like this, at least enough for a couple cappas.
It takes a little practice to get used to when the light is going to go off, so you can start steaming before that happens, but the sound of the water boiling inside is a pretty good indication. If I miss it, and the light comes on, I'll just flush a couple oz of water, which cools it off enough to turn the heaters on.
Replacing the steam wand with one from a Silvia also made a huge difference. The arm is longer, and it has a proper single hole tip which really helps to manage the steam pressure and get good microfoam.
