This is what I did and it turned out great for my conquest points and my ffxi exp.
I leveled all my jobs to 37. This did alot for me...
1. I had a ton of conquest points afterwords 2. I had ALL jobs available for a sub job and 3. I had the chance to get the feel for how all jobs are handled and played so it overall gave me a better ffxi exp.
Additional by bjhix Very good answer above - fact of the matter is there is no EASY way to get CPS (Conquest Points). Like everything that is worth anything, you have to "work" for it.
And additional suggestion would be to do every Out Post supply quest that you can do. It not only grants you access to that Out Post should you chose to OP Warp, it also earns you CPS
