That is if there advanced enough to hear us, i mean 20.5 light years is a very long way away, and it would take generations to get a signal back from them if there was intelligent life, but does that make it any less of a reason to try?

Remember that SETI is privately funded - that is, funded by donations. They scan as much of the sky as they can, but those who want them to do more need to either donate or encourage their government to help fund the program.

Well, Gliese 581 c is theoretically inside the biozone, but two conditions are not favorable after all:
- likely tidally locked (same side towards star at all times)
- very active parent star (BY Dra type), liekly with strong flares
That'd result in a pretty inhospitable planet, really.
Thus, it's rather doubtful higher, let alone sentient and technology-oriented life might have evolved there.

I think they should be scanning across all the radio band to see if there is any thing coming in.
Within the book The Source by Art Bell and Brad Steiger, it talks of an incoming message when a particular frequency is used. It has been determined to NOT be terrestial, and we have been picking it up since we started using radio in the late 19-teens and early twenties.

You can be sure that SETI will exploit any opportunity that may increase their chances of receiving an intelligent signal.
