Very nice!
1. As low as you can to do what you need. A few hundred, a few thousand, it depends. For towers, depending on how far you want to detail it really.
2. Again, depends. A detailed tower going to have bigger texture than an empty cart for example. Vanilla banished uses 1024x1024 texture atlas for buildings. I would not advise ever going bigger than that. If you're going to use multi material meshes, 256x256 would be the smallest I guess, depends on the level of detail you want.
