In my humble opinion, your frees could use a boost. Armour is good option and might do the trick. I would postpone introducing any heart meds, until you have finished messing with your t-protocol. To change over, you best bet is to lower the levoxyl, and add in some Armour gradually over time -- Not cold turkey. That would be bad...and would put your body through hell.
I would test frequently, and tweak a little every few weeks or so.
I wouldn't pay to much attention to the TSH as much now. It doesn't carry the same relevance it would if you still had a t-gland and no meds.
