Hi Mattrox,
Looks OK, but a few comments follow.
I haven't got Beersmith with me at the moment to work out OG, but given the quantity of fermentables I'd be inclined to make a yeast starter and/or use two packets of yeast. Also make sure you oxygenate well by splashing as much as possible when you're filling the fermenter. These two things will help attenuation so you don't end up with something overly sweet.
Can someone with Beersmith on hand do some calculations about whether this beer will be sufficiently bitter (
IBUs of Coopers can thread)? I am not sure whether you may be sensible to replace some of the malt extract with dextrose to cut down on residual sugars and therefore sweetness, or to add some extra hops. The Coopers Lager can is not that bitter. An alternative would be to use a kit with higher IBU.
You might also investigate getting
Beersmith yourself. If you don't want to fork out for brewing software, check out
BrewMate, which by most reports is a pretty good program.
Cheers,
Oliver
