If the iphone and ipad have different Game Center accounts, you could connect that way :) Just make sure to be friends :)

As for co-starring anyone with a is a co-star. No one is the "Best Co-star" so just pick who you wish to do a project with. The more co-star points you earn with indivdual co-stars, the more rewards you will earn with the co-star levels :)
