Formed tracks between Strahan/Zeehan and Marrawah

I'm thinking of deviating from the main road for this part of the walk so I am after a bit of local knowledge.
Are there any formed walking tracks or gated fire trails through here that will keep me off the public roads and 4WD tracks?
What are the best hard copy topo maps for this area and who sells them?
