English-Arabic-English Dictionary

Hello all. Hello moderator DrSyR75.  I'm new here. So let's get down to business.

I need someone with a lot of experience in Arabic (either a teacher who teaches through English or a proficient English-speaking Arabic student) to recommend me a English-Arabic Dictionary and a good grammar book written in English. My Arabic background is 11 years of almost exclusively theoretical learning at school, i.e. I know a lot of the grammar (but still need to brush up on the sarf) and it wouldn't be difficult to learn other new tools that the Arabic grammar can offer. My vocab is rusty. I've considered buying a grammar book written in Arabic, but doubt that it'll be of much use, at least at this stage.

Thank you so much.
