If you can turn a screw and not strip threads you should be fine. They are just like any other threaded feature you have used, you just need to be a little more careful to not damage the threads. Use a small amount of wood glue when re-installing to both lubricate the threads and take up space in the threads, do not over torque! Some people use epoxy, but this is overkill and can to lead to tearing out threads for future removal. If there is minor damage to the threads when removing the old bindings, you can mix some wood dust into your wood glue for extra strength and use even more caution to not over torque. This is also a good time to check for "volcanoing" of the holes. If they were originally mounted sloppily there may have been a small amount of material at the topsheet pushed up kinda like a shallow volcano or a zit, which can cause the binding to not sit flat on the ski, increasing the precious stack height of those bindings. I use one of those curved yellow scraper/planer things (typically sold by all of the other planers in the hardware store) to make sure the top sheet is flat and then make sure to get all of the debris out of the hole (also great for scraping PTex repairs). Or you could do a slight countersink but you need to be really careful because it is really easy to go too deep with a countersink into the short threads.
