Against his raising range, I have a 44% equity + a good postflop playability. So, is this preflop play correct? What about the postflop action?

Against his raising range, I have a 46% equity but he is very aggressive and will bluff a lot. So postflop, I will fold lots of hands when I'm ahead because there are Overcards. How should I play this hand against very aggressive bluffer?

In my capping chart it says that every pocket >99 is worth a cap. But here I have the same problem again. It is this super aggro bluffer in front of me. I'm sure he will bet the flop, no matter, if he hits it or not. And if there are overcards I'm in bad shape 
I can't fold it but downcalling can be a expensive situation.
