Re: DENTS (how bad are they???)
Generally, dents at the bow (bottom of horn) don't make a lick of difference as to how it plays unless the dent goes so far as to malign the tonehole - making it unlevel.
Dents on the neck are more sensitive, but small dings are not normally of concern anywhere on the horn. How big across and how deep is the dent on the neck? I've played on some really ugly necks that sounded great on the horn.
