help understanding pluging and what is possible

CRM 2011 on premisis & SQL2008R2

We currently import about 100 xml files from a third party into our CRM system on a daily basis into a custom entity. I have written a SSRS report that currently is manually executed for each new entry and the report is saved as a PDF and emailed out to our customers. I have been trying to write a plugin that would auto create the PDF files, but can not get it to work.

When a record is imported into the entity, I have a process that extracts parts of the data and creates a record in a monitoring entity

Question.

1. If a plugin is registered on 'create', will it be fired if the entity record is imported?

2. does anyone know of a step by step tutorial that i can follow.

The code below for my attempt at a plugin, causes the import to fail. The report is a simple report for testing and does not take any parameters ( well i need to walk before I run ) . Any help or suggestions would be appreciated

attempt at plugin
