you just go around the place beating up the team rocket grunts
You have to defeat team rocket in the suspicious shop, nw of the guy 1st. Then fly to goldenrod city, and go to the underground. Talk to the rocket grunt, and youll change into a rocket grunt suit. Talk to the rocket grunt blocking your way upstairs in the radio tower, and you have to defeat him, and the rest of them. After that whole process, fly back to mahogany town, and the guy will be gone, then you'll be able to challenge the blackthorn gym.
first, you have to catch/defeat the red gyarados in the lake of rage, then you talk to lance and fly back to mahogony, then you defeat the electrodes and team rocket members in the souvenir shop, then you beat the gym, then you defeat the team rocket base at the radio tower in goldenrod, the you can go past the ragecandy bar dude
You go and ask the "rocket" over near the flower shop(at) the flower shop and go to the tunel and were the camara man was.
in mahogany town there will be a gift shop that says on the sign [just a gift shop nothing to be suspicious about.] When you get team rocket away from the lake of rage a red haired kid with spiked hair [not your rival] will tell you to go to the gift shop and he will push a shelf and there will be stairs for a basement and that's where team rocket's HQ is.
First you need to defeat team rocket in mahogany town in the souvenir shop. They are under a big statue use strength and move it. where it was is a whole go in in and defeat them. P.S I would recomend being lvl 20-35 they are tuff
Once you capture or defeat the Red Gyarados at the Lake of Rage, return to Mahogany Town and enter the Souvenir Shop. Lance will proceed to open a passageway that leads to Team Rocket's headquarters.
go to the lake of rage and capture or defeat the red gyarados and lance will appear on shore and tell you to meet him in mahogany town then you go into the souveneir shop in mahogony town and you will find a secret hide out then you have to defeat team rocket. at least that is how it is on soul silver.

first beat the gym in that town then professor elm will call. after that go to goldenrod beat team rocket then move on to blackthorn to beat Clair
Definitely not under the Souvenir Shop with the TV antennæ oddly placed atop a nearby tree & no TV inside! Like the sign reads, it's : "Just a Souvenir Shop Nothing Suspicious about It No Need to Be Alarmed"
