Not to be too negative, but I think it might be a bit ambitious to get someone with no technical background up to speed on the entire web development lifecycle

Not to be too negative, but I think it might be a bit ambitious to get someone with no technical background up to speed on the entire web development lifecycle quickly. Being an effective web project manager is software project management; it just happens to be client/server software with a very, very large installed base of clients. I would focus less on specifics of servers and implementation languages, and more on numbers 3, 4, 5, 7, and 9. If he can focus on the information architecture, usability, and overall project workflow, a decent design and engineering team can support him in the rest.
