Thank you both Rudegar & Diavonex for responding. I spent all day working on this & finally figured it out.
I had restrictions set on the ipad (bc it's for my son) & set it to restrict installing or deleting apps. DUH.
I changed it to allow installing & deleting apps, and am now gladly, happily, joyfully installing 27 apps!
Thanks for all the help!
(on to my ancient itunes2 to modify the settings on that!)
