Not sure on the bolt placement. I'm sure someone here knows for sure.
As far as the coolant being everywhere YES- clean it off ALL pullies before you reinstall the belts or you will have massive belt slip/squeal that will most likely never go away and you will end up buying new belts (not cheap). In fact, I would clean everything you can on that side of the motor while you have access to it. Not only will it look better but if you have a leak somewhere after reassembly then it's easier to tell where it's coming from on a clean motor. If it's all black then use some engine foam and spray it down. Most likely you probably have power steering fluid leaking down there too which adds to the mess. And possibly the rear valve cover as well.
And before I forget, since you didn't label the bolts you now see why it is important. I'm not doggin ya, its just a lesson we all have to learn. What I often do when I take something apart for the first time is leave the bolts in the part that it came from that way you know for sure that they belong in that particular hole and not somewhere else on the car. Of course this usually only works on parts that you have removed, but you get the idea.
Worst case scenario grab a paint pen and label the bolts w/ numbers and label the matching holes on the bracket the same way.
