Are there ends to the electro-magnetic spectrum, or are we just not able to detect beyond our capabilities ?

Whats beyond cosmic rays, whats the longest EM wavelength possible?

There are no limits to wavelength. Of course any wavelength that is seriously long is extremely difficult to detect as you would need an aerial hundreds of miles long. Very short ones are rare as the energy involved is very high.
