Is it worth while to use Agents or not?
No, it's not.
Using agents is not about building a distributed system, it's about whether you want to architect your system around units of autonomous behaviour, with their own goals, strategies and beliefs. There's nothing in your description that says that you would need that extra complexity to solve your users needs.
My advice: don't focus on how you're going to build your system, focus on what your users need. Then make the simplest technology choices that you can in order to meet those needs. As you build your application, your understanding of your users needs will change, and your application will have to change with it. The more complexity you build in from the get go, the harder it will be to be agile in responding to your changing understanding of the problem.
