So I just tracked down Benny at New Vegas and stuff. However I'm only lvl 10 and I'm coming towards something that looks like some of the end quests. I'm only lvl 10.

Is this recommended to do it? or should I lvl some more?

You finished Act 1 which is nothing but "find the guy that shot you and deal with him". It's little more than an introduction.

As for what is "recommended"... do whatever you feel like doing. That's the point.

I got there right at Level 10/11

And, just because you talked to Benny does not mean you are anywhere near the end of this game. I would guess about 1/3 through the MQ depending on how you handle all the interested parties.

The beauty of the game is that you can get to Vegas pretty early if you want to, or you can hold off and do tons of other stuff leveling up first.

It's about personal preference and play style, so really if you're more interested in the main story, I'd say you should keep going! If you enjoy the side quests and exploring, do that!

Thanks a lot guys

LOL, I'm the opposite.. I was lvl 24 when I finally made it onto the actual Strip. I guess your character was more focused on finding out why he/she got shot in the head than mine. I was very easily distracted by all sorts of other quests, maybe a side effect of getting shot in the head?
