The current space for items and eidolons hits 400 now afaik. You don't exactly need the space until you've acquired some SR or SSR weapons (for skill enhancement reasons, consult Sanahtlig's guides for more info on that) that eventually eat up the initial 40 slot you get. Same applies for your eidolon space. So in general, just roll more until you feel your inventory gets clogged up too fast.

As for the actual account... to be honest I don't see anything too special with that, afaik Eros isn't exactly a game changing SSR or a core light element, and you don't seem to have any extremely significant eidolons on hand either. I would re-roll for core himes (again, check Sanahtlig's guides, he covers those aspects too) or 100% atk eidolons.
