I have a small garden pressed up against my south to south-west wall. There is snow all over the yard, but the soil for at least two feet from that wall is not only bare, but it's soft and warm(ish). I'm thinking it'll be okay to start peas now.

However, this is also the spot I plan to climb pole and/or runner beans. Is it feasible to plant peas maybe two feet out and later on, the beans just inside that? I'm thinking a lower trellis for the peas, and a higher one just behind that for beans.

Will the peas be done and out of there in time for the beans to flourish?

(is such a wall/spot too hot for pole beans come summer?)

Oh, and I thought I'd throw in some perpetual spinach along the wall. They'll be shaded later on by the bean trellis.
