Kara
 

I heard Kara is pronounced more like 'Kala'.
Is that right or am I just hearing it wrong?

That's hard to answer as we don't know how you pronounce 'Kala'. How do we even know you are pronouncing the 'Ka' part correctly, let alone 'ra' (or 'la')?

I can tell you this for sure, though. If you're saying から then you are saying it perfectly.

Not especially, Lolx5

The Japanese R is somewhere between L and R in terms of method of pronunciation so I can understand the confusion, but I dont think there is any real difference (certainly none you should worry about) between kara and any other word. (plus kara is such a recognisable word, it would be hard to be misunderstood).

How much Japanese do you know? If you're still in your first 3 years or so of learning Japanese, then I wouldn't worry too much about exacting your pronounciation yet! If it really bothers you, try listening to Japanese radio or TV for "kara", and try and imitate it.

it's neither an L nor an R. it's something called an alveolar lateral flap which is pronounced kind of like the r in Spanish's pero. Though, in my personal opinion, at least, i think it's more of a tap...but i digress.
you may want to try fixing your pronunciation. even if it doesn't bother you, it bothers me.
