That red arrow is pointing to the "suction accumulator" which is where surplus refrigerant liquid is stored while the unit is operating. That part should be one of the last areas of the evaporator to get frost on it.
The blue arrow I can't really see what it is pointing to! The black arrow clip looks like it should indeed be supporting that line. Looks like someone has already worked on this unit; or the factory assembly techs built this one on a Monday or Friday LOL!
You're very unlikely to find any current HVAC techs who will charge this for you. It is sad and wrong, but it is how things have gone. If you decide to go DIY you'll have to likely do the whole job, including getting the correct tools to do it. There are no shortcuts around having the correct tools, by the way.
EDIT: An typically, the cold-control is reliable. You can still get replacements for this, as well even if it goes bad.
