I'm not scared of trying new things--like changing my o2 sensors so the engine light will go off!! Any advice for someone who is a novice, but likes to do things herself?

herself?? haha nice, not too many "hers" on here... welcome. im not familiar with 99 cruisers but cant imagine its too different from my '92 pickup. take off the 2 bolts and swap-a-roo

oh by the way.. what makes you think that the o2 sensor is the cause of your check engine light??

Places like Autozone will read your check engine malfunction (for free) and tell you the code, which will let you know what component is the problem. No sense in wasting money on stuff that doesn't need replacing. Good luck.
