Now, pair your K-1 to an FA 31... shoot your combo everyday for (say) six months, then return to the forum with "What's next..." questions.
my 2 cents (and what I'd have done, if I knew what I know now and a do-over was possible)

Almost what I was going to say, except I'd go for the D-FA 50 macro - an excellent lens, small and as sharp as you can get. And as Michael suggests, just leave it on for weeks and see where you end up. Though the 28-105 is supposedly a good lens, it is a compromise, and personally because of its wide range might create bad 'zooming' habits.
