See you're from Pa. Highly suggest you join the PTA, in the 570 area you might be in dist 9 same as me. You'll get the monthly trapper magazine and regular postcards about local events like fur sales, mini convention, and meetings. There is also the annual PTA state convention. That's a good place to start, also the HPA forum has a trapping forum and it is quite active, don't know if you're already on there.
For land animals I use traps up to 1 3/4 size, mostly MB450 and MB550's. But they are expensive traps. I use both offset and regular jaws. Lures? who knows, they all work for some of the animals and none work for all the animals, you'll need a variety.
http://www.patrappers.com/The link below is a wealth of information about trap sizes based on collected data, an excellent place to start, use the menu list on the right side of the page. If you closely analyze the data in the BMP's you will find that the 1 3/4 size trap shows up as one of the recommended traps for every Pa land species.
