In terms of software, try maemo-mapper.
A receiver that supports more channels isn't necessarily better. The number of channels refers to how many satellites the receiver can track simultaneously. There are only 32 satellites in orbit (only 31 actively transmitting) and a maximum of 12 can be in view at any point on the earth at one time. Any 12 channel receiver should work just as well as a 20 channel. As far as a 51 channel receiver goes, I'm sure it exists, but only because they know that most people will think it's better because it has more channels.
