I know very little about Summoners and Eidolons, but if the latter can wear items, a Golembane Scarab is a great investment for the modest cost.
As far as DR/cold iron or silver, I don't know your level, but an Amulet of Mighty Fists +3 would allow your attacks to bypass those. Might be too expensive, I don't know.
Silversheen...that might be a DM call, but it would be far cheaper than the AoMF.
Good luck.
We just got done with a "dungeon crawl" so I might have the gold depending on how much we get. Thanks for the suggestion!
