As I understand it, the problem is that you want to be able to select the AF point different from the AE point.
You can do that with the K3 if you can accept to do AF and AE in two separate steps and that AF is performed before exposure measurement (no need to move camera in between).
Here are 3 simple ways, assuming AE already is linked to AF, spot, automatic exposure (Av, P etc.) and using live view:
1: First move the AF point to where you want to focus. Then push the shutter release halfway down to focus. Then move the AF point to where you want the exposure to be measured. With the default configuration for the AF button ( = cancel AF, Camera settings->4->Button Customization->AF Button->Cancel AF), push and hold the AF button to cancel AF, release the shutter and take the image. For the next image (without refocusing), move the AF point, push and hold the AF button, release the shutter, repeat for each image.
2: Pushing and holding the AF button while pressing the shutter release for each image can be avoided if you change the AF button behaviour to AF2 (Camera settings->4->Button Customization->AF Button->AF 2. This disables AF with the shutter release and AF must now be performed by pressing the AF button. So now you must move the AF point to where you want to focus and press the AF button to focus. Then move the AF point to where you want the light to be measured and presse the shutter release button. Repeat for each image.
3: If you have a remote control, it will (by default for setting C.3.19) release the shutter without refocusing. Now you can focus by pressing the camera's ordinary shutter release button halfway down, move the AF point to where you want to measure light and trigger the shutter release with the remote.
Then, there is a snag with using manual exposure (M). You can then measure light with the green button after you have moved the AF point. However, before pushing the green button you have to lock the AF point (remove those arrows on the AF point) or else the green button will reset the AF point to the mid point of the live view instead of measuring exposure.
Hope this was of some help.

I like your option #1 the best.. but after some tinkering I think I found a quicker method.. kinda sloppy but Ill have to try it!!
1. Link autofocus and exposure.
2. Go into live view and use movable spot focus to set your focus pushing shutter button halfway.
3. Turn switch on camera from Auto focus to Manual focus.
4. Move focus point to point of desired metering... camera will remeter but not refocus... take shot..
5. Move focus to next point and continue...
