I agree that you'll probably have to do most of this research on your own. I doubt that you'll find a tire/rim combo that is lighter than stock with 35s because the stock alloy rims are pretty light.
You'll want to pay attention to wheel material when shopping for a wheel. There is steel, cast aluminum alloy, and forged aluminum alloy. Steel is heaviest but also cheapest. Generally steel rims will bend rather than crack on impact which is good off road, but some have complained that the modern steel wheels tend to be thinner than they used to be, resulting in more problems off-road. If you're on a budget and looking for something light and strong cast aluminum is a good way to go. Although they have more of a tendency to crack on impact offroad, very few people ever have an issue with a cast aluminum rim. You'll probably be able to find them a little lighter than the stock rims if you search around. Finally, forged aluminum rims are more expensive but they're also stronger than steel and cast aluminum (all else equal) and they also tend to bend rather than crack on impact. Some forged rims will be way lighter than the stock rims, but be careful to get one that is not too thin that it cannot handle large tires and off-road conditions.
As for tires, you'll have to search around, but I agree that in general Interco tires are on the heavy side. I have some Interco SSRs, however, and can say that they do well in the snow without chains. Other mud tires that I've heard are good in the snow are Firestone Destination MTs and Mickey Thompson MTZs. I'm not familiar with the "traction control tires" symbol, but you'll want to look for a mud tire with siped tread blocks for good snow traction. Let us know what you decide on!
