Place a small delay or reverb on the TM88 Hi-Hats, so then the Kick will cut through more subtly. Also, EQ the Hi-Hats somewhere around 500Hz and 2kHz to keep a cleaner mix. As for the pitching, I would take some of those high frequencies out as well. As for the Pierre Bourne Clap, you should layer that with another percussive Clap, and place a parametric eq, and turn on the attack. I would also set up a high pass filter, if I were you.
A good tip for your 808s are, if not given enough space, they will make your beats sound very muddy. So for that, I would try sidechaining the 808 to the kick, so that the 808s duck, when the kick plays. Keep track of the release times, and amount of compression used, it has to be just right.
