Hello,
There really is no right or wrong answer for where you place effects in your signal, it is up to the artist and what type of effect they are trying to achieve.
The H300 Factory plug-in is a multi-FX processor, so depending on what effect you are using you may want to use it as an insert on a single track, or use it as a bus/aux send effect and send multiple tracks to be processed at once. EQ/compression could be place before or after (or before and after) the H3000 depending on the scenario.
The best advice I could offer is to experiment and find out what works for you and whatever you are working on.
