A CRJ-900 flight crew was left too high for a stabilized approach after responding to an RA on approach to TPA.

Narrative

After working around weather into TPA; and being assigned 3 different arrivals; we were left high during vectoring by Approach...we were just coming to the base of the clouds in our descent when the Controller called traffic and gave us a turn toward the traffic...we told him we were still IMC and rolling out on the assigned heading the traffic popped up on the TCAS at 500'...as we came into IMC conditions we spotted the traffic just as the TCAS indicated 400' and gave the 'monitor vertical speed' command...we told Approach we had just complied with an RA on the traffic...he said nothing other than to hand us off to another controller...we were asked if we had the airport in sight; cleared for a visual but were by then in a position that wouldn't allow a stabilized approach to 18r...so we executed a go-around and landed shortly thereafter without incident. From the time we got to JAX Center's airspace it seemed as though they were conducting controller training or something...the weather wasn't so bad that aircraft deviating should've been a factor...and from one freq to the next the controllers didn't know what the last one had done with us...3 different arrivals in a short time and left very high for our proximity to the airport.
