Hello wireless networking community! I come to you with a question about increasing the signal strength and range of a home wireless network that exists between two houses. Information about our current network is listed below, including a satellite picture of the two houses.

There is a Linksys E2000 wireless router at the marked location in home 1. I have a Linksys AE1000 wireless usb adapter plugged into my computer at the marked location in home 2. Windows usually shows 1/5 bars signal strength on the computer in home 2. If I connect my iPhone 4s to the network, and leave the room (where the AE1000/computer reside) in home 2, and head down the hallway to the family room (to the west), my phone disconnects from the network. INSSIDER shows a RSSI of -80 to -90, and a Max Rate of 54 on the computer connected through the AE1000 usb adapter.
I'd like to be able to connect to this network with a solid signal throughout home 2. What hardware/software changes do I need to pursue to make this happen? Judging by the scale of the satellite image, the distance between E2000 router & AE1000 adapter is currently ~100 ft. Also, according to a rough estimate, I'd like to be able to have solid signal strength through home 2, which is maximum ~200 ft. from the E2000 router at any given time.
Thanks!
