How can I concatenate strings and variables in a shell script?
stringOne = "foo"
stringTwo = "anythingButBar"
stringThree = "? and ?"
I want to output "foo and anythingButBar"

Nothing special, you just need to add them to your declaration.
For example:
stringOne="foo"
stringTwo="anythingButBar"
stringThree=$stringOne$stringTwo
echo $stringThree
fooanythingButBar
if you want the literal word 'and' between them:
stringOne="foo"
stringTwo="anythingButBar"
stringThree="$stringOne and $stringTwo"
echo $stringThree
foo and anythingButBar
If instead you had:
stringOne="foo"
stringTwo="anythingButBar"
stringThree="%s and %s"
you could do:
$ printf "$stringThree\n" "$stringOne" "$stringTwo"
foo and anythingButBar
