Yep it is important. If you decide to do it yourself - USE A TORQUE WRENCH - don't just crank it on. Over-tightened lug nuts are more dangerous than under-tightened ones. The under-tightened ones will give the symptoms you describe and usually some warning that something is wrong. Over-tightened ones stretch the studs and are more likely to fail without warning (studs snap and wheel goes bye-bye).
Also Superflyer, that wheel should be pulled and the studs checked. If the wheel was wobbling around - which it was - it can easily cause damage to the studs. In fact, if it were mine I would replace them regardless of how they look.
