You only need to install shutters with a frame if you do not have enough window depth clearance to install the shutter inside the window frame directly to the window frame jamb or if you don't have a solid wood window frame b/c it's not a good idea to afix the hinges directly on top of a drywall opening.

Mhanna is correct. You can install shutters on frames on the trim outside the window. This is what we often do and have never run into problems with this mounting method. Before you do this, however, place the frame of the shutter on the window just below the crank. Turn the crank a full 360 degrees to ensure that the frame of the shutter will not interfere with the turning the crank after the shutter is permanently mounted. If you want to see some diagrams of framed shutters, take a look at the following: Plantation shutters: Atlanta

Depends, ultimately, on how they were attached and glued in. If you are careful and don't apply over pressure to the frames, you should be able to salvage them and move them. Keep in mind that the frames are designed to support any weight and are basically decorative until they are installed on the window. They are quite flimsy in most cases so less is more here when it comes to the amount of elbow grease to apply.

I love interior shutters (eagerly waiting for mine to come in!) and absolutely disagree with the notion that they are light blocking bohemoths. With the variety of options that they have today, you can find something to fit lots of different scenarios. My house has a ton of great natural light, and I'm going to be preserving a lot of that by getting 4" louvers, which, when in the open position, let in lots of light. You can find shutters that open completely in a variety of configurations, from single panel to two panel (that open in the middle to each side) to bifold, which are popular for those that will be opened frequently as they take up less space on the adjoining wall. They also make them where you can open the top and bottom louvers independently of each other, so you can leave the bottom closed for privacy and the top open for light, and also open completely independently of each other. You may have some windows that you feel will stay closed much of the time and get a single panel for those, but two panel or bifolds for windows that you may want to open more frequently. I sound like a commercial, I know, but I really do love them. They are definitely a particular "look" and so obviously won't appeal to everyone, just like any other design style won't appeal to everyone. But for me, as a person who really dislikes fabric and fussiness, I think they add a lot of character and charm. In answer to your question, OP, I think they will look fine with your windows.
