Gear shouldn't be an issue especially for EV and KP, but mechanics and finding a group might be a little more difficult. Most ec hm pug groups would be hesitant to bring in a member who doesn't know the basics to the flashpoint especially if they are unsure of the person's pve experience.
If you're unsure about jumping strait into the hard modes, I'd definitely recommend trying the story modes first.
They're pretty easy, and you might be able to meet some people who will be able to take you through the harder runs. Just try to follow directions and observe properer operations etiquette. I don't know much about how much pve you've done, but a few hm flash points can help ya get the knack for it too.
