Without ratings it will be difficult to give you perfect recommendations on an offense or a defense. However, given that your team is unbalanced and your main players appear to be perimeter players then an outside offense would be best. Run 'n' Gun is probably serving you just fine. Defense is probably more about gauging your opponents.
Advice Turn Up never asked for:
The most important component to conquering the V leagues is to learn how to balance your roster to keep game shape high and managing enthusiasm. That's going to give you a large advantage by itself.
In terms of your roster, my advice is to balance out your roster. Think like San Antonio Spurs, limited money and making prudent choices in creating a well rounded team that can play any style of play. In lower divisions there is a lot of variety in tactics and personnel choices, so it's advantageous to have a balanced team that can adjust tactics to defeat opponents.
Something to remember with V leagues is that if you are a dedicated player, you're probably going to promote quickly and there is a strong chance you'll be retooling your roster upon promotion. Thus, if you feel a older cheaper player will help you save money toward that retool, that's fine.
