Are these important or can they wait?

While looking around on the project 88 I saw a line next to the BA10 (L side ) that wasn't hooked up. Can someone tell me what this is and does it need immediate attention?

Also, next to the bottom left of the rad I saw this unhooked device.

 

There are many other questions I will have in the near future. Thanks for any help.

Top picture is the bleed valve for your the internal slave cylinder...its like the bleeder for your brakes

 

next picture looks like a connector for an Automatic Trans line on the radiator...since you have a 5spd its not needed

Thanks. So I guess I can drive it without trouble from those two items at least. Good to know.
