What you propose nets +2 crit range +1 multiplier (as well as more spells), but it costs at least 53 APs so it restricts what you can do with the rest of your points. Beast Awakened is 23 APs in Nature's Protector; that's what lets you cast druid spells while Raging. [Unless you're a Wildhunt Shifter, in which case you can take your racial ability instead.]
The THF and Shield Mastery / Shield Bash feats do nothing in animal forms. However, the THF feats do unlock the Angry Arms + Mad Munitions + Focus Wide enhancements and their Strikethrough bonuses will carry over to bear form. Also a dwarf who uses dwarven axes in bear form will benefit from Strikethrough bonuses from their racial Axe enhancements; but hand-and-a-half weapons do not increase their base damage modifier with Natural Fighting feats in bear / wolf form the way they do with THF or SWF feats in humanoid form.
