Unsure about the use of backslash here.

Do I have to use a back slash \ for ( and ) or these < > below?

/^[a-zA-Z0-9#$%^&=\[\]()<>\/_-]{8-16}$/

I have two books I can refer to. I can take the time to do research but the reason I ask is I don't have the time. Expert Exchange costs me money - the point of which is to save me time.

No, you don't have to use the backslash for those characters. This is because most of the characters that are "special" in a regex lose there "specialness" when inside a character set (ie. inside the square brackets [  ]  ).  Note though that the backslash IS used for the square brackets though, because otherwise the regex engine wouldn't know if you wanted to match a closing square bracket  ]  or if that was just the end of the character set.
