To be honest, I used to shut my two out of the kitchen when I was cooking etc. However, we have got to a point where if they look like they are going to jump up, I hold my hand out, palm down and say 'no' very firmly. It doesn't always work - it depends what I have on the side and how desperate they are to get to it. Obviously with two it was harder to control them when they were younger, you'd get one off the counter and the other one would appear - so it was just easier to shut them out. And then we'd have to run with our dinner and shut them out of the dining room as well or they'd be trying to steal our dinner from our plates! But they grew out of that, thank goodness!
It is a good idea to move your kitten onto the cat tree though - he has a place he is allowed and if you reward him only there, he should get the message very quickly (hopefully!). Bengals are very determined creatures though and if they really want something they are seriously persistent!
Going to back to toys etc, my two were never very into the Kong kickeraoo's - however, I bought another Kong toy recently that is definitely a good wrestling toy! It is a Kong Cat Scratcher, and when the cardboard is shredded, you take it off and its just a cuddly toy. I think Jagger prefers it as it is solid and he can really get tucked in to beating it up!

The other thing I do (as you can see from the mess beside Jagger) is a cardboard box with packing paper - they love that, dive bombing the paper, hiding under the box lid etc - I put some of their toys in it as well for them to find etc. If you get a laser pointer I used to use that over a pile of packing paper (which I used to buy specifically for this purpose!) and they loved that.
You will find out what your kitten is in to - get some coloured springs, they love chasing them and Hendrix is big on playing with bouncy balls and will play fetch endlessly. It's all about wearing them out with 'good' play in order to avoid boredom and idleness as that is when they look to get into things they shouldn't
