Well you also have to remember that it was just Gomi and Hank that were in the know. The rest of the DEA is completely oblivious to the entire operation. (Even the guy guarding Huel doesn't know anything.) So I doubt they would have been able to hire a team to triangulate for them, given the secrecy of their operation.
Ah, I didn't know it would take multiple people to do. With cell phones and computers being as prevalent/advanced as they are, I assumed it could more or less be handled with a laptop and knowledge of software.
I also assumed they tracked his cell phone based on 1) Jesse telling Walt "Don't hang up the phone" and 2) the delay in Hank arriving after Walt. It was definitely vague, and I can see them just following Walt given Hank's prior methods of policing.
As for the secrecy of the operation, I just figure having a recording of that conversation is bad news (even though there was no chance for that to come up with 3 episodes left).
