No idea on the sword since almost all of them get too big for my aquariums. Since you're dealing with low light, this may be a non issue since swords generally require at least medium light. You could check out PlantGeek.net's Plant Guide to try to ID it.
Anubias are slow growing especially in low light aquariums, but eventually they do get bigger. It's taken my Anubias Nana 2-3 years to get to it's tank busting size under medium to high light. That's with my taking the occational cutting too.
As far as plant selection goes, if you're in the US, in about another month you'll probably start seeing a lot more plants being offered up in the barter trade section as it gets warm enough for those of us in the northern states to start shipping trimmings again. This would be a good way to get ahold of some plants inexpensively that you won't see in your
LFS.
