Your paragraph at the end tells me that you are a little uncomfortable still in your new limit. This is totally normal. My advice is to fold this and in all situations like this until you really know what to expect from your opponents. Guessing is never good in NL, and too often all of us tend to make the bad and more expensive choice when we're confused and think we might be getting played with. It's pretty normall to think that people are bluffing their asses of at the next limit up. Let the paranoia wear off before making big decisions to commit a big chunck of your stack.
