Southern Myanmar's infrastructure is poor especially in the deep south. Basically all major towns are link by highway #8. Every town will have a street with bus ticket seller. The bus station however is most of the time out of town. Buses run daily. Minivan services have started to serve major town connections. They are slightly quicker than buses and seem to pick you up at the hotel. The only downside is that the vans are not made for Western body sizes.
