What is the best way to go about removing this rust and restoring the area back to somewhere near its original state?

Once rust has taken hold, rust proofing is analogous to throwing the baby out with the bath water. When the vehicle is Factory fresh, rust proofing can be used to coat/seal metal from the rusting elements. If used AFTER rust has begun, it simply speeds the rusting process by sealing it in.
Additionally, if you try to remove anything more extensive than surface rust, you will weaken or pierce the metal, completing the damage the rust has begun. Of course cutting out the rusted sections and replacing or welding in new is great, but you will be sadly surprised how much cutting out you will have do and it is very expensive and long.
Your best bet is to use a rust converter. These products react with rust and convert it to a hard non-rusting metal byproduct. The surfaces must be clean of oil, grease or dirt contamination and for this I would suggest a marine degreaser/etcher. After that, you can use the converter. Coat the areas carefully, leave for 24 hours to cure fully, and coat again.

P.S. Do NOT go near POR-15
