If I had to pick one guy among the rumored names - it would be Hamels. This pitching staff just doesn't have the horses. After Lester the only guy who has pitched a full season + playoffs is Hammel. That said, the payoff of a deep playoff run for the Cubs will be massive. They should do bat and impact arm, and really kinda have to. This is definitely the year to do it. The public on a national scale has never been more interested in what Theo and friends have been doing, and I assume they can get bored if nothing happens. Spend some money and prospects at the deadline to make some serious money for the next half decade+ off of a playoff run... Totally agree with the bold; they need both. That said, both would cost too much, even with the resources they have, so I'd prefer to deal big for a bat and then, hopefully, deal smart for a decent pitcher.
