Seems like you are on the right track with the above posts but just one point to remember - nearly all profiles for cichlids will term them as semi aggressive or aggressive but this is just the case with these fish compared to tetras etc. Cichlids should be thought of as intelligent or territorial rather than aggressive because they are usually not just nasty animals that will bite chunks out.
Housing larger cichlids are a different ball game to the smaller fish and the community will be set up around the cichlids as the center.
With regards the Blue Acara - its actually their close relative the Green Acara which is Central American, their northern habitat is actually part of their classification as a species.
With the high ph in your tank I would go for Central American cichlids that dont get too big. I put this in a post for Mark a few days ago but a similar mix would work for you Heryithcys Deppi, Cryptoheros Nanoletus (yellow convict), Theraps Coerleus and Thorichtys Aures (spelling on most lol sorry) But yeah I just think that a group of those as singletons would look a nice mix against some general community fish like the schools and catfish - this is not an exhastive list by any means but just some of my favs
