Best auto trans. o/h kits in your opinion?

There aren't any. You'll need selective thrust button between the front and rear shaft ends. Also you probably have five direct frictions; most kits have four. Even the red eagle kits that have five for the direct aren't advisable because once you make the step to smooth high performance plates (they can withstand higher temps) you might as well opt for forward frictions; which are thinner (.061 vs .086); allowing six frictions in the direct clutch. There's a five plate direct kit on ebay for 204.87; you might inquire as to the thickness of the direct frictions. You'd probably be better off ordering ten alto red eagle forward frictions separately; that is if you want to order parts before you take it apart. Also the thickest middle thrust button.
