With the schedule you described, it doesn't sound like you're purely a developer. Either a lot of this stuff needs to move from your plate to someone else's, or you need to accept that you do a lot of non-development work. Note that of the distractions you describe, a lot of them are things that you would have still had if you were working from home. The emails and the IMs are still there, although I guess they might be more ignoreable since you don't have the threat of the person showing up at your desk. :-)
