Im thinking about tuning 3 steps down to B E A D. Will a 50-110 gauge set be alright for this or should I look at heavier gauges? Also, should my bass be re-setup to accomodate the difference in tension?

Generally, you'd want to use the bottom 4 strings from a 5 string set, so a B string between 125 to 135 gauge. Of course it depends on whether you like lighter gauge strings and the scale length of your bass!
And yeah, you'd generally want to adjust the intonation and the neck relief for a different tuning
