You have a few options... Do you want to go the software, software with hardware controller (hybrid) or hardware route?
i make boombap now and my (main) weapons of choice are Native Instruments 'Maschine' (software with a dedicated hardware controller) and a turntable.
The other software/hardware combo worth looking at is the Akai 'MPC Renaissance'
On a budget I'd look at the Maschine Mikro (same software - smaller controller)
Lots of videos for both NI & Akai on YouTube.
If you want to go straight hardware (no computer) then
the Akai MPC1000/2500 or the Roland MV8800 would be my choices.
If on a budget you could get going with a Roland SP555 and a turntable.
Software DAW would depend on you OS (Win or Mac?) and workflow preferences but plenty of try before you buy versions around...
On a budget then look at 'Reaper'...
midi keyboards - literally hundreds to pick from - I'd go basic if you get Maschine/Ren etc but if just using a DAW something with more knobs/faders etc
Soundcard (audio interface - ignore if going full hardware - essential if using a computer/laptop) 2in/2out and some monitors (monitors are good) and you're pretty much set
