Alembic's wood page is the best source of info if you can find it. Coco Bolo (or cocobolo or cocobola, there are many ways to spell it) is the same wood used for the top of Tiger & Rosebud. It's warm in tone, with an emphasis on low mids IIRC. It's also very heavy and oily, requires extra care to glue because of the oils, and the sawdust is a skin & respiratory irritant.
About fretboards - Rosewood is very warm, Ebony is brighter and tighter, and maple is even brighter and snappier than that. Rosewood is getting pretty scarce so there are a lot more substitutes out there than actual Rosewood these days which are sometimes mislabeled - Pau Ferro and Ziricote come to mind. Warmoth's site has great info on fretboard woods, and also make fantastic necks if you wanted to swap one onto your Strat or Epi.
