Simple title page - would like to add a logo

I have been using Docbook for just a week or so to create a user manual. 
I am using the DEP4E Eclipse plugin to author the Docbook text. DEP4E is using Docbook 5.
I only want to create the output in two formats - Eclipse Plugin Help and PDF.

This question relates just to the PDF output.  

All has gone well and I would like to now add a logo to the left of the title but so far have been unsuccessful at accomplishing what initially seemed like a  simple task. 

So my first question is this even doable - or must I get into the realms of XSL customization to accomplish this?  

I am not sure how flexible DEP4E might be in allowing a customization layer to be created.    

Ideally, I would like to format the book title to be approximately 1/3rd down form the top of the front page but I will worry about that later once I get a handle on if the logo can be inserted.

Sorry if this is a dumb question but picking this up has been a learning curve. 

Thanks
