Personally, for something like this I would use ESPN. The interface is easy to use, it has links to the ESPN site, and is generally easy to use. But, the best reason for a league like this, is that they do offer lineup advice and recommendations and the projected stats appear to be better than a lot of sites out there. Almost like driving an automatic car, they can let the site take the lead on a lot of decisions and start assuming the amount of control that they are comfortable at the pace that they prefer.
I'm in a local redraft league on ESPN and I swear that at least half the league lets ESPN make all of the decisions for them. And ESPN has been doing a lot better than me this year in that league.
EDIT - I just took a look at the lineup optimizer. I'm not sure if you need an Insider subscription for that but it gives a projected win percentage based on either your opponent's current lineup or "optimized" lineup. It will then offer suggestions as to who to start and explain why it made the decisions. That could be very helpful for new players -- if you trust the recommendations which i don't always. But it helps new players start thinking about why certain decisions are being made.
I have pasted a screenshot of the lineup recommendations below. The greyed out players are recommendations that ESPN made. And, although not formatted nicely here, there is a link to "Why did Insider make these recommendations."
