I think that's a darn good start.
Needs improvement though.

Land mines and mustard gas. Nerve gas and gas masks are better, but you are at the mercy of the wind.
Must haves in that sort of situation. Make sure the machine guns are good ones. Barrels melt, ammunition jams - gotta be ready, and a farm is a tough thing to defend with less than 10 people.
All that stuff takes a ton of maintenance.

I got that part down. The cool thing is that it is STILL less than 15 minutes from TWO walmarts and one Lowes!
