Would the remaining elvish strongholds help Eomer and his exile riders?

I don't think Theoden's view of Elves is much different than Eomer's - or any of the Rohirrim of their time, before the events of LOTR. It comes down to their cultural attitude towards Elves: we see it exemplified in Eomer, but he just voices the superstition of their people. Besides, being Wormtongue's puppet is a score against Theoden.

As for Eorl, he seemed like a guy willing to try weird and different things, who wasn't content to play it safe. In UT he seems less trustful of Lorien's good intentions than Borondir when he passed its mist, but he was also not particularly convinced that it should be evil. So perhaps if he were to turn into Lorien he would have kept a more open mind, or at least a more courteous manner, than would Eomer.

May I ask you a question in turn: why do you imagine these characters seeking aid in Lorien and other Elven Kingdoms? What would be driving these characters to the situation you describe? Why Elves - as opposed to other Men, who are much more familiar to the Rohirrim? And what would Eomer (Theoden, Eorl) be seeking with these people?
