Everything Brian said!
Re the cables, get some bitter apple spray. Everything else - it's time to get really tidy and minimalist. Put things away like headphones etc. Anything left lying around will be thoroughly investigated by a Bengal and 'checked' for durability!
How many litter trays do you have? Are they scattered around the house? He's a baby so you need to make sure he can get to one easily. Just like babies, kittens will have accidents, or bengals will be so engrossed in whatever mischief they're up to, they don't realise they need to pee until it's too late.
Things getting broken or damaged is going to happen unfortunately so anything you value highly should be put away.
Bengal kittenhood can be a challenge, but eventually they do calm down a little.... Not much though
