Build files, keymap entries, and `run_latex_build.py` plugin for adding the option for running bibtex and cleaning up auxiliary files for LaTeX in Sublime Text 2. Added the ability to run bibtex, and changed key bindings.

Bibtex.sublime-build

{
    "cmd": ["bibtex", "$file_base_name"],
    "path": "$PATH:/usr/texbin:/usr/local/bin",
    "file_regex": "^(...*?):([0-9]+): ([0-9]*)([^\\.]+)",
    "selector": "text.tex.latex"
}

CleanLatexFiles.sublime-build

{
    "cmd": ["latexmk", "-C", "$file"],
    "path": "$PATH:/usr/texbin:/usr/local/bin",
    "file_regex": "^(...*?):([0-9]+): ([0-9]*)([^\\.]+)",
    "selector": "text.tex.latex"
}

Default (OSX).sublime-keymap

[
  // Run bibtex
  {	"keys": ["super+shift+b"], 
    "command": "run_latex_build", 
    "args":	{
              "build_system": "Packages/User/Bibtex.sublime-build",
              "reset_to": "Packages/LaTeXTools/LaTeX.sublime-build"
            },
    "context": [
                { "key": "selector", "operator": "equal", "operand": "text.tex.latex" }
               ]
	 },
  // Clean up LaTeX auxiliary files.
  {
   "keys": ["super+shift+c"],
   "command": "run_latex_build",
   "args": {
            "build_system": "Packages/User/CleanLatexFiles.sublime-build",
            "reset_to": "Packages/LaTeXTools/LaTeX.sublime-build"
           },
  "context": [
              { "key": "selector", "operator": "equal", "operand": "text.tex.latex" }
             ]
  }
]

run_latex_build.py

import sublime
import sublime_plugin

class RunLatexBuildCommand(sublime_plugin.WindowCommand):
    def run(self, build_system, reset_to):
        self.window.run_command( "set_build_system", {"file": build_system } )
        self.window.run_command( "build" )
        self.window.run_command( "set_build_system", {"file": reset_to})

@dpo: I think it was a hangover from running separate LaTeX and BibTeX commands the "old-fashioned" way, but sometimes it's convenient to run just latex or bibtex without invoking the switch in focus to Skim, i.e. if you're essentially just "debugging" the LaTeX source.
