Dear god that is a HUGE question
You have 2 partners but you don't want to reply on them too much? Sounds odd to me. I let coders code, designers design, and I get on with what i do best.
Why do you want to learn coding and web editing software if you have partners?
Seems to me you need to define what the roles of each person is before you take this partnership forward. UNLESS you are saying that they are 'partners' in as much as you pay them to do work but they don't own the business.
Careto clarify this?
