I'm sure you'll manage it with just EMP grenades and the barrells. I know it took me a few tries when I was in that situation though.

Well, upgrading Hacking: Capture to Capture 5 is a must. That means you won't be locked out of hacking any object. If you want to avoid being detected while hacking, thus increasing your chance to successfully hack an object, then upgrading Hacking: Stealth is really useful. To be honest, I've never found it necessary to purchase many of the other hacking-related augs so unless you have loads of spare Praxis points, I wouldn't be bothered with Hacking: Analyze or Hacking: Fortify.

The cloaking aug is great for stealthing for obvious reason, as is the run/sprint/jump silently upgrades. One useful augmentation that might not be so obvious is the lifting heavy objects one. There are often big crates and stuff in front of vents that will block a more stealthy approach to a level so it might be worth getting that. Also, since the cloaking augmentation uses so much energy, you should upgrade your energy levels too.

Stealth Enhancer is specifically geared towards stealth players obviously but it's up to yourself if you think you need it. I often go without it during stealth playthroughs.
