I've never seen a snow plow in my life. But down here people have large, custom bumpers with large winches mounted in them. Get some beefier coil springs installed. If you leave it on year round you could leave the springs in, but if you remove it in the summer you'd need two sets of springs.
Tundra springs will fit on a Tacoma strut, from what I've researched. People use them to lift their front ends and I would, but I haven't been able to source any from local junkyards here. If you remove the plow in the winter then you'll have some serious reverse rake. So you'd need to raise the rear in the summer and get an alignment, or go back to the stock springs. I would avoid a front leveling kit since it's the added weight of the plow making it bottom out. Stiffer springs are the answer, as well as having two sets (the stock ones, and the stiff ones). Removing and installing struts that are made up can be done in an hour after you've gotten the hang of it.
Hope this is helpful, and can you post a picture. I'd like to see this snow plowing Tacoma.
