Why is this listed as just "必要" instead of "必要はない"? "必要" by itself doesn't line up with the listed meaning or structure.

The second meaning (slightly further down the page) is 必要がある, so 必要 is the common element that they both share :)

What about Noun + が必要だ formations like this one? for example:
お金が必要です。
I need money.
okane ga hitsuyou desu.

I didn't put this in originally because it is not a unique expression, just a noun + が  + adjective. Since 必要 is up here, though, it wouldn't hurt to add it!
