You can "donate" extra eggs and monsters at the Keepers Stronghold by talking to the blue person in the screenshot. This process gives smaller rewards upon donation, and larger rewards on getting a certain threshold of army strength donated. Donation is also great to keep your monster inventory clean if you don't need extra copies of common monsters.
Stores will sell better items the higher your Keeper's rank is.
The Infinite Arena (also found in the Keeper's Stronghold in the fuchsia-colored) gives reward boxes, which contain items, potions and eggs! This is a great place to "farm" experience and some harder-to-find items.
