I need some advice on abnormal pap smears--never had one before?

Needs follow-up. It needs to be checked. The viral assays are changing the protocols. The test is a screen for cervical cancer and pre-cancer and as such is very sensitive -- but please do get the follow-up your physician suggests.
More workup. If a pap smear is abnormal, colposcopy is done, with 3% Acetic Acid painted on the cervix. Abnormal lesions are seen as white patches. These are biopsied, and examined under a microscope for possible malignancy. If there is cancer in situ, a cone biopsy is done, which is therapeutic.
