The offset is how far from the center of the wheel the mounting surface is "offset" or distanced. Positive moves it towards the outside of the wheel, and negative towards the inside. So the above example is correct.
Honda's typically have a fairly high offset in the mid +30's to high +40's even. Anywhere in that range will be fine if you are using a 7" or narrower rim. When you get wider than that, you need to be careful that the extra width that you're adding doesn't move inward towards your suspension components and interfere with operation during turning. But if you take too low of an offset (like +10 or something lower, let alone negative), you can end up having your tire hitting body panels when the suspension compresses, or if your ride is lowered, the inside of the fenders when turning hard.
one benefit of lower offset is that the wider stance it provides. Aside from the wider tires, the wheels will sit further apart from each other, which widens your base of support and increases handling, usually. Too wide of offsets and wheels can negatively affect your handling however by giving feedback thru the steering system - such as a jerk on the steering wheel from bumps or uneven roads. Also wider wheels will become unbalanced more easily. That however shouldn't be a problem with the wheel sizes that fit on the tegs - reasonably anyways.
So a safe bet for 7" wide rims would be a PCD of 4 x 100, with an offset of +42, but lower down to say +35 shouldn't hurt.
