I'm gonna go right out there and say no.
I have looked for articles on a similar level and they are very hard to come by. I think people don't like to give away all the information, so you can't steal their jobs. Or they just like to be at the top.
I will say to first build a lot of your engine, isometric or otherwise. It seems easier to find articles on isometric tiles than square tiles, but that may be because it is considerably harder to implement.
Once you have something up and running, it may become clearer what you need to do. Ask questions at this stage. gamedev.net is probably a good place to ask.
Remember that in a 2D engine, as well as the height stuff is implemented, it's still just a 2D representation of a 3D terrain. All you have to do is give the illusion that it's a 3D world (whether it's purely visual, or affects gameplay like the disc throwers in C&C:TS).
