If your shifting at 1500 rpm that sound your gettting is the synchros grinding because they are not synchronized. Unless the trans is well broken in I would not shift at that low of an RPM. The synchros require some RPM to create friction to be able to synchronize. Shift at least over 3000 RPM or at a high enough RPM that gives you a smooth shift.
Don't force the trans into gear if its grinding, let it go in on its own with a light pressure. If you force the trans into gear while its grinding your going to end up with bits of metal in the oil that will make shifting even harder. If it gets real bad shifting it maybe time to change the transmission oil to try and get the metal bits out. The transmission gears are always in mesh, it is the synchronizer collars? and whatever that lock the transmission into specific gears.
Let the clutch fully out before getting on the gas. The car rocking back and forth is the clutch springs or rubbers taking the shock of engagement or the clutch bouncing if your on the gas before the clutch is fully engaged/released.

Also is this transmission soposed to be loud? Like hear shift clanks as i change gears? Or am i messing up my tranny. When i am actually driving and i start out in first. When i get into the very last part of letting out the clutch, its like the car rocks back and fourth. Why?? This dont happen all the time but am wondering what im doing wrong.
