There are a couple of ways to do everything.

For the Stop sign False, you can just hover your cursor over the Stop sign input node, right-click and select Create->constant.
That'll give you a simple boolean and you can switch it between true & false by clicking on it.
(It won't look exactly like the one in the picture, because the picture one is actually a control from the front panel, but you don't really need that.
If you really want that one there are two additional clicks you have to make: Change to Control and then unclick View as Icon.)

The arrow is found on the Programming -> Structures palette.
You will have to reverse it by right-clicking on it and choosing change direction.
The rhombus square thing underneath will appear after it's wired, but in the latest version of LabVIEW it now looks like an asterisk.
