Alright, I felt compelled to give some sincere opinions to balance out the Oprah crack. Er, the crack about Oprah.
Strides? Sure, they're almost always good during any phase of training for almost anyone.
Stretching? Different people seem to have widely varying needs. You should have some idea what worked for you in the past. Of course you're older and chubbier now, for whatever affect that has. I'll suggest this: you'll be doing more slower miles, which means less range of motion, which I suspect means more need for postrun stretching.
Once your base is there? Dude, four months starting from zero plus a beer gut, you barely have time to build a partial, mini, better-than-nothing base. It's not like by week three you can say "aha, there's a solid base; now it's time to add strength then speed then taper."
Threshold? My suggestion, especially considering your very limited time frame and starting point, is to kill two bird with one stone - focus entirely on marathon pace runs. Opinions vary but mine is that substantial MP runs are at least in the same ballpark for working on your threshold as faster "hour race pace" work or whatever. And they'll acclimate you, physically and mentally, to the pace.
Of course that begs some questions, like what's MP for someone with no recent PRs or workouts or even base mileage; and will your actual race pace be much or any faster than your daily training pace anyway? I dunno how to answer these but suggest generally that you consider longer, slower "tempos" and not these "20 minutes at 60 minute pace." The longer tempos have more relevance for the longer race. I'm thinking more like 40 to 80 minutes of a good solid effort, but well shy of all-out.
Repeat miles? IMO only if they don't significantly detract from your more important training goals: total volume, long runs, long moderate tempos. Again, you don't have a lot of time and you're not going in with any kind of fitness; you've got to prioritize and make some hard choices. You can't do it all this time out.
Hills, though. Don't avoid hills! I wouldn't worry about hard hill repeats - you might be begging for injury trying them at this stage - but if you can consistently cover some nonflat topography on your daily runs and tempos, they'll help. On your recovery days (I gotta think you *will* need some, after long runs if nothing else) keep it easy effort and flat though.
