The manual says it can be rechared 300 times. Does that mean its useless after 300 times charging?

Rechargeable batteries all have a lifespan. Over time they will deteriorate and hold less of a charge. Anything with a rechargeable battery that is not replaceable will be defunct after some period of time. 300 charges is the mtbf (mean time between failure) rate, meaning will last about that many charges. However, given several months per charge, this is still several years. You could use one that is battery operated, and thus buy batteries every few months instead.

I lost the usb dongle receiver, is there anyway I can get a spare one?
