Answer 1

Your approach is fairly normal Clojure code. One other choice is to use promises or if you need more complex processing you could consider using something like lamina or if you feel like living on the bleeding edge you could try core.async:

(ns async-example.core
  (:require [clojure.core.async :refer :all])

(defn example []
  (let [a (chan)  ; a channel for a to report it's answer
        b (chan)  ; a channel for b to report it's answer
        output (chan)] ; a channel for the reporter to report back to the repl
    (go (! a (rand-nth [true false])))
    (go (! b (rand-nth [true false])))
    (go (>! output (and ( ( ( (

Of course this is overkill for your situation, though it's tremendously fun anyway ;-)
