Issues our agency is having - would like some insight

Our agency has some issues with our production when it comes to Zoho projects. Here are our problems. Any insights, tips, etc are appreciated. 

1. Task Dependencies - we want to create task lists that have tasks that are dependent on the completion of another task. We thought this was possible but it assigns the task out anyway without the dependency being met. Anyway to fix this?

2. Task templates - we have task templates that are pre-assigned with dependencies. These templates have LOTS of tasks so when they are plugged in, you have a lot of tasks assigned to you, even before the task dependency is met. 

3. It's really a jumbled mess in our back-end. We don't check our tasks as much because we have so many. What is the best way to go about organizing our projects, tasks, milestones? 

Our agency does website design, SEO and advertising. So, anyone in a similar field want to share their process? Thanks.
