MNM 1.9 economy

[pannonian]

Asking for tips from expert MNM players. I'm playing as Rome, on BI.exe, VH campaign M battles. It's quite a shock finding the longer, different, more expensive tech trees, which has meant I have difficulty building. Can anyone offer any tips on what is the key to economy, and how ports compares with farm and mine upgrades? Do Shipwrights and Dockyards add to the sea-based economy, or is that based purely on the Sea Control line of buildings?
