Question : How to setup network

A friend of the family setup my network and is no longer contactable. We had a fire and have had to replace our routers at the house. I need help setting my network back up. I have an office at the back of our property which I have internet for which is connected to an Asus router. The house has a new router indoors (D-Link DIR-300) which will be connected by ethernet cable from LAN port to LAN port of our new router outside (Edimax BR-6204Wg Wireless-g Broadband Router) which is then connected to a large directional antenna (was safe from fire). (I don't understand why we have both equipment. Perhaps to ensure connectivity throughout the whole house. There was an ethernet switch between the two, but I'm hoping we can do without it.) Anyway we want to be able to setup a network at home so everybody in the house can connect wirelessly to it that can access the internet from the office network. What do I need to do? How do I setup the two home routers? A step by step guide would be great, including what SSIDs to use. I'm at a loss. At the moment the two home routers share the same network name as well as channel. I wanted to keep the house network seperate from the office network. If I attach the big antenna at the house to a USB Wireless Adapter on my laptop I can connect to the office network. However when I screw in the antenna back to Edimax Router we have no internet via the home network. Please help!
