What crimp tool is needed to crimp these?

Make sure to use a crimped for coated connectors. If you puncture the coating they will no longer be waterproof. If that doesn't matter the regular butt connectors are way cheaper. Use these for wet applications and marine for sure.

what temperature is needed to shrink these? Will a hair blow dryer work or is heat gun needed

Hair dryer, heat gun, lighter, mini torch all work.

The crimp provides both mechanical and electrical connection. If you're asking this question, this is not the product for you.

Can I use soldering iron instead of heat gun?

Very hard to get good result with soldering iron. A small torch if you have one would be better. Heat gun is the right tool.
