Obviously armor doesn't provide its bonus in wildshape (unless you use the enchantment from MotW) but does a ring of protection, amulet of natural armor and the like continue to provide AC bonues if a Druid wildshapes?
Are there any inexpensive ways to increase your AC while in wildshape?
All equipment merges uselessly into your wildshape form. Unless you pick up a 4,000 gp Wilding clasp (or something like that -- an item that prevents attached amulets and cloaks from melding into a wildshaped form), the only way to keep them effective is to remove them, wildshape, and put them back on (or have a helper put them back on you).
As for useful ways to increase your dex: go the spell route:
1) Purchase a wand of mage armor for the party wizard, to splat you with before you go adventuring.
2) Trade spells with the party wizard: you cast barkskin on her, she casts cat's grace on you.
3) Trade spells with the party wizard or cleric: you cast barkskin on him, he casts protection from evil on you.
If you do all these things, you'll end up with +7 to +9 to your armor class (+4 mage armor, +1 to +3 cat's grace, +2 protection from evil).
