A Comanche was my first vehicle too! (sorta, had a couple hand-me-down Fords ahead of it) Still have her 23 years later!
I would stick to the basic maintenance until you've got a handle on what all she needs. Keep reading and learning, especially make sure you cover all applicable Cruiser's MJ tips found near the top of the link in my signature.
And don't forget to take her to car shows!
