help with roadrunner+netscreen firewall+cisco router

Ok - after my router got hacked into a few months ago - i took it out of the network and used my computer as a residential gateway/firewall for my network. I recently aquired a netscreen 5GT firewall (only has the console, trust, and untrust ports). I also have a Cisco 831 broadband router. My biggest problem is that i cannot seem to configure the firewall properly to allow any access past it. I've tinkered and toyed with everything i can think of but I cannot seem to get the device to let my computer through it to the internet. Does anyone know what i may be missing? Here is the config for the netscreen (after the basic setup and a small amount of experimentation):

The router I should be able to manage once i find my old Cisco book and remember how to configure one from scratch from the command line (the CRWS doesn't work anymore). If anyone can help me with the firewall (essentially that's all i want it for is for the firewall/filtering options - I use my cisco router for the home network internet access) I would be most grateful! Thank you for any help!
