thanks for the response,
i can probably say more about reggae in the development of hip hop than salsa or other latin musics, but the reason that I added the Nuyorican bit is for one because latinos played a key role in the development of early hip hop in new york, places like the south bronx were centers of diverse communities that included large numbers of caribbean and latino first and second generation immigrants, all of which were active in the early days of hip-hop--this kinda defies the idea of hip-hop as a purely "african american" artform. I also have seen some great footage at a talk given by Pop Master Fabel in Montreal a few years back that draws connections between salsa dancing in the 1970s and what would later come to be referred to as "breaking". - also, some initial googling turned up this book, which i havent read, but seems interesting (perticularly chapter 6)
From Bomba to Hip-Hop: Puerto Rican Culture and Latino Identity
By Juan Flores
probably worth a read to dig deeper into this question
As far as hip hop being related to reggae, my understanding is that Kool Herc brought the Jamaican soundsystem model to new york and turned people on to the idea of mixing records on 2 turntables, which led to people rapping over the resulting combinations of beats, pretty similar in a lot of ways to what was happening with Jamaican music at the time with the era of the deejay in full swing. one of my favorite articulations of some of the many and often pretty confusing connections between hip hop and reggae is wayne&wax's writing (in general, but specifically) about the zunguzeng theme (i like his little mix too) check it out if you havent:

just some thoughts, I'm not a historian either, i have just always been curious about hip hop's relationship with its (less obvious) relatives. of course, its also important to recognize the connection between early hip hop and "african american" artists like the last poets, gil scott heron, watts prophets, melvin van peebles etc.
and about african hip-hop, ive always had a hard time getting into it, I've heard a good deal of rap in wolof, but never could really get into it because i dont understand the words
