1. Work breakdown structure https://en.wikipedia.org/wiki/Work_breakdown_structure
2. Try not to plan too much further than 30 days.
3. Try not to plan more than 80% of your capacity. Beyond 80% capacity you will be late on everything because of the nature of queues.
4. Look for bottle necks in your process. Is there 1 person out of 20 that is doing all the renderings? You will need to plan careful to avoid work backing up at that persons desk or you will need to train a few other people to help out when a backlog develops. Otherwise that bottle neck will lead to delays on multiple projects in spite of being below capacity overall.
After that, it really doesn't matter what tool you use to manage it. Post-its, Basecamp or Project. Pick your poison.
