Upgrade your R29 Innovator so you can use Requirement Engineering R33. With the previous version you will not "run" but stumble around. RE R33 introduces drag&drop and this version is much more intuitive to use. If you plan to upgrade, wait a bit more for Innovator R37, cause it should hopefully introduce relationship tab counters, which will help you a lot. Don´t let them fool you with R33-R36, they are fine for RE, but I would wait for R37.
I don´t use RE in a production environment, but played around with the app. In general I would customize the feature in a few corners. Example: Current RE adds two relationships to the Part ItemType. "Requirements" and "Requirement Documents". From my POV it´s an obscure double structure that will be confusing and hard to maintain on the long run. Which one of the relationships shall we use? In my case I just would use one, or auto fill the second one.
Don´t see an Aras app as something that will always fit your way of working to 100%. The apps are like unisex T-shirts that fit most people somehow, but may not be perfect for your exact body shape.
