Looks good. Looks pretty good.
There's one more rule I forgot to write.
- above 60º, the currents will also have the tendency to turn Westward

Still, I think tectonics before climate is a better route to follow. With a tectonic model you can determine where you have continental shelves (which will add detail to your currents pattern) and you will have tall mountain ranges (which will add detail to your winds pattern).

Anyway, as for wind / weather. Have you read this?
The Climate Cookbook

It's an awesome DIY guide, a must-read I got pointed to from this forum.

And also, have a hard look at pics like this:
