Congatulations on getting your new Chi! :P
Tucker does not like rubber toys at all. He likes soft stuffed toys---he has some with squeakers, some without. He also loves small cloth balls that we can play fetch with. He has a nylabone, a flavored one, and he chews on it sometimes, but he really loves Greenies and small rawhide chews. Tucker likes baby carrots and bananas for treats (just little bits when we're eating one ourselves), and he also gets 1 or 2 Milkbone puppy-size dog biscuits a day, which he enjoys.
