Can you land an asteroid

Should I even bother with trying a low energy transfer, utilizing Mun to get to Minmus?

No. Minimus has an eccentric orbit. Attempting to gain a gravity assist from the Mun that will provide the exact normal/antinormal force to end up in a good Minmus encounter at the exact right point of it's orbit will require some very exact calculations.

The most efficient way I know of is to match the orbital inclination before making the injection burn. From a parking orbit of approximately 100km this just happens to be as it rises over Kerbin.

You could do this in the config file, but it's easier to make this change in game (although you may have to do it each time you switch to it). This requires that you have a docking port pointed in the prograde direction. If you do, right click on that, and select Control from here, and you're done. The gimble will flip, and everything will be pointed in the correct direction.

If you don't have part that you can do a Control from here on (and is pointed the correct way), then it is possible to make the change in your persistence file. In a text editor, open %KSP_DIR%/saves/<save name>/persistent.sfs, and under the VESSELS section, find the probe you want to edit. Find the PART section for the probe body, and change the value for rotation. I don't know the format for that value*, so this could use some experimentation, but set it to 0,0,0,-1 and see what that does.

^{*I don't have time right now to test this to tell you for sure what it should be, otherwise I would.}
