The first thing to do is to call Customer Service
with your list in hand. They like documentation in the form of e-mails and e-mailed photos if possible, but it looks like you won't be able to document the two examples you gave with photos.
They can give you some options on repair, I do know that they will authorize non-Newmar service centers to do repairs, for example, if you know of a mobile repair service in your area they would probably authorize them to do some repairs.
We had most of our warranty service issues dealt with by an authorized Newmar service center about 120 miles away we did not buy the coach from, in fact they had decided to drop motor homes and concentrate on trailerables during the recession. They were able to handle things relatively efficiently, we did have to leave the coach with them. Approval for warrranty repairs took a couple of days, parts took from a week to two weeks depending on the supplier.
