1) We're still looking. It helps to find planets so we know where to look. Space is big, really.
2) By 'water' I will assume you mean water in its liquid phase, because water in solid form has been found all over the place. Its common as muck.
3) As soon as you can tell me exactly what you mean by "like earth". Do you mean with oceans and land and nitrogen/oxygen rich atmosphere with white and black sand beaches and restaurants where the steak overhangs the plate on 3 sides? If you mean have you found a planet which you could beam down to without breathing/life support gear (and live), then no, not yet.
As for the discoveries being hokum, it sounds like you're waiting for the ULTIMATE DISCOVERY. Sorry guy, but its all incremental knowledge that will let us find the big stuff. Finding important stuff in hard to find places a long way away tends not to be done "by accident" but by years of hard work. Any idiot can discover the moon on his own, but can you honestly say that you could have discovered that the Earth moves around the sun, and not the other way around?
Would you spend the years in careful observation, with meticulous record keeping, facing the storms of "intelligent criticism", to collect enough data to prove your point to the world that your crazy idea makes sense? Lots of professional people do, they are scientists; lots of other people do too, they can be hobbyists; lots of crazy people do too, they may be just crazy.
There is no substitute for hard work in scuence.
