The Known World or, The Lands between the Grand Castellate

[Adolon]

This is for a project I've been working on for many years but up until now I had no map. As I said in a previous thread, I had a world but no idea how it looked. With some help from here, I finally got to where I was happy with what I had created. Attached is an equirectangular projection of the landmasses and the Grand Castellate, a 24,000 mile wall that goes from pole to pole and back again, cutting the entire globe in half.

I'm looking to make a world map with two hemispheres much like a Blaeu map I have framed. In my imagination, it would include latitude and longitude lines, place names, legend text, et cetera.

I'm posting here because I need some help. Of course. I'm having a hard time fiddling with Photoshop and even Illustrator. I know Fireworks like the back of my hand but its limitations (such as memory and file size) are getting the best of me so I branched out to Photoshop (64 Bit) and Illustrator. But I can't seem to get around them, like how things I could do in Fireworks I can't replicate in Photoshop/Illustrator either because it's impossible or involves a technique I'm not familiar with. I own CS5.1 but never really touched the two programs. Any help would be appreciated.
