Once I have decided on a particular panel I then need to decide parallel or serial connecting the panels. The shade issue with serial connected panels worry me plus I'm being told the Morningstar 60AMP MPPT charge controller "might" not be enough.
Like Mena said, MPPT will clip the excess amps off. You will lose those clipped amps on "some" hours on "some" days in summer. Not all the day, and not all days, and not in spring-fall-winter. On those days that you will lose it, it will be maybe 5% of total daily harvest because it will be clipped for a few hours only. No big deal. But, if you need to get all the energy that there is, - get a bigger controller.
I wouldn't worry about shading of series vs parallel. In all those endless debates there has been no clear consensus on the subject. I tend to think that parallel is a little better, but if this complicates the work too much, wire them in series. 1,000W is a lot of energy, with partial shading this is still a lot with either wiring type. If you're worried about not getting enough, better optimize your consumption side of energy budget - especially kitchen. Lights and heating too.
