We are constantly finding more and more planets that may contain complex life. My question is if we do run across one that is equil or greater than earth in the sense of intellect, what type of communication would you expect to find? Radio Waves? and does anyone know what the first type of communication that Earth sent out?

Generally radio waves can be used by those civilization. but if they are very intelligent than i think that those "people"
have realized that there are many other sources for radio waves in the universe so if by chance we get the radio waves than we will get confused by the direction "mainly it could be possible that it came from other sources for e.g. satellites". hence they could have a very brilliant source for communication which is different from all other sources for communication. like sending some unique wavelengths of electromagnetic radiation.
