Have a look at
http://www.boxing4free.com/ for basic technique.
Also have a look in the stickies for hand-wrapping so you dont mess-up your wrists.
Personally, I'd "invent" my own routine based on what skill level you are at. Eg; as a beginner myself, I so far am only practicing jab, cross & hook as well as a MT low kick. My routine starts with 5 minutes skipping, the 3 min sets+30s rest (as per King Kabuki's routine) however - as that routine was too complicated for me I just work on the above. Only a few sets but I start light then go harder (therefore I might repeat the sets). It's not really very formalised but it might start with jab only 1 min, jab+cross 1 min, the jab+cross+hook 1 min. Next set is normally R kick (light), then L kick (light) then 30s L +30s R (hard), the 3rd set is jab+kick, jab+cross+kick, then jab+cross+hook+kick. I'm still toying with it all...
