I guess if I didn't have to take the pill in any way, shape or form, I wouldn't. A family member had a stroke two years ago which was directly related to birth control pills (she also hit all the risk factors for having a stroke on the pill, which you may not, but still, a stroke at 35?).
I don't know that you need a "plan" as badly as you think you do. If hubby has had a vastectomy, then really the planning is around your comfort level and nothing else. While comfort is important, it really isn't' the be all/end all as say an unplanned pregnancy.
I'd stop the pill at least so you can share with your doctor as the outcome of doing exactly that. It's not like you can't go back on them if your first period lays you up as bad as you are worried it will and then discuss with the doctor in a couple of months.
I'd also check into just taking care of the matter with a hysterectomy (full, partial, ablation, whatever) - I had a hysterectomy in my 20's and literally have not regretted one second of it (I'm approaching 50 now). There would be no way that I would still be on the pill nearly 30 years later.
Good luck!
