I don't want to sound dumb but I've never shot a bow that required anything smaller than a 2216 arrow and I'm rather lost.  I now have this cute little 60# Grizzly and I'd like to shoot it but haven't a clue as to arrow size.  I'd like to shoot aluminum so any suggestions.  My draw is nearly dead on 28".

Try a 2018 at 29.5" Start with a 125gr tip. You can go with shortening the arrow or use a lighter tip if the arrow is not stiff enough. Or use a heavier tip if the arrow is too stiff.
