Advance to large nodes using the roles that correspond to the bonus you want. There are some "perfect" guides out there but it's not that hard to do on your own. Most people use all STR bonuses for Noel (until the very end of the Crystarium since there are more large nodes than STR bonuses) and all MAG for Serah.
As for DLC, Lightning's Story gives you a good COM early I guess (I beat the game before most of the DLC was released). Don't worry about Colosseum fights until later. Sazh's Story is good if you want to rack up casino coins easily.
