Best Approach for Master/Slave Form SELECTs

I want to have the second select options dependent on the selection of the first select option. Is this built into Rails? I haven't seen it.

I'd rather not right JavaScript and Ajax to pull values in background unless necessary.

No.

It's necessary, but not difficult. You put an observe_field on the first select that calls a controller method when the select changes, passing along the value selected. The controller method (re)renders the second select via rjs, either inline in the method or via a separate rjs view. Search the list archives. The question's been asked / answered many, many times.
