Answer 1

It is indeed an insect, not an arachnid. The red part is not a "butt," it is the insect's abdomen.

For a species ID, you should ask the Bugman:

Answer 2

It is a Wheel Bug, which is a type of Assassin Bug. The picture that you have is the nymph form. It is not a spider. I advise you not to touch these as Assassin Bug bites can be painful.
