Replace turn signal/combination switch

2000 Chevy Impala. 125,000 miles.

I purchased a replacement switch for the turn signal because the high beams wouldn't stay on. Does the steering wheel have to be removed to replace the turn signal lever? I found one site on the net that says its just a matter of removing two screws, dropping the plastic cover behind the steering wheel and then removing the switch. Is this correct or should I have a professional do it? I was quoted $130 to do it, but money is so tight right now and I have some mechanical experience.

EDIT-
I forgot to mention that this switch doesn't have the cruise control on it. The cruise control is on the steering wheel.
