Congratulations! You can't go anywhere anymore :)
for the last achievement (not kongregate, but the game itself), you first have to be fully upgraded, and then you fly up with your rockets, in an angle that the speed stays the same while raising altitude. when you're rocket is out of fuel, you have to keep flying that same angle, untill you reach around the 100mph. then you have to fly a little bit down, so you keep the speed of 100mph, that way you will reach the 6000ft easy =D
