I'm looking to buy the JLT Performance Cold Air Intake and the SCT X-Calibrator 2 from MT.com. Along with the one tune that the SCT comes with I wanted to add one additional tune, essentially the exact same tune only set to use 93 Octane fuel.

Considering that as of right now, the only mod I've done is to replace the stock mufflers with a pair of SLP Loudmouths, do you think I would need to take my car in to a local Speed Shop to do a Dyno Tune, or (not to sound like I'm dissing MT.com's technical skill & knowledge or products here by the way) would the tune(s) from MT.com be "good to go" so to speak?

If MT.com's tune(s) are "good to go", would there be any benefit to be gained by going to a Speed Shop anyways after installing the JLT and the tune?

If you suspect it running rich or lean, I'd have it dyno tuned but at this stage I don't think its necessary for you. Just be warry of any knocking or pinging. I haven't had mine dyno tuned but but it runs like a monkey so I figure the a/f can't be too far off.
