Kepler22b-first exoplanet found in hab-zone of sun-like star

Is it possible to find out if kepler is solid or gaseous or is that something that our instruments cannot now detect.

Not with the Kepler data. It will require further observation with different instruments. If we can determine it's mass that should allow us to make a reasonable guess. Although if it's only 2 1/2 times the size of Earth, it's reasonable to assume it isn't a gaseous planet. I think at least.

But do we have those instruments available to us now, or do we need to invent new technology in order to get that data?

I think we can get a lot of it, we just have to wait for more orbits, which takes time.
