I don't really know about #1 - do you think he is bolting his feed and not chewing properly? It could be that he might be trying to Choke - that would definitely require a Vet visit. I feed Triple Crown Low Starch and I wet it really well (warm water in cooler months) and that works well for my guys.
#2 is a tough call since unfortunately, a lot of very serious eye problems look EXACTLY the same as minor ones. I can only guess if the eye is watering, it is painful - there could be a scratch on the cornea that would require antibiotic ointment or possibly a cortisone ointment might be needed depending on what the cause of the irritation is - again, you would need to call your Vet.
