Need help with fantasy starters

[Captain Chaos]

Got a few questions that I need second opinions on.

Should I start:
Roy Williams against Chicago, Antonio Bryant against St. Louis, Drew Bennett against San Diego, Troy Williamson against Carolina, or the surprising Jericho Cotchery against New England?

Also:

Should I start:
The disappointing Drew Bledsoe against Washington, Rex Grossman against Detroit, J.P. Losman against Miami, or Damon Huard against Denver?

one last one:
Heath Miller against Jacksonville or Desmond Clark against Detroit?

You are probably saying my team sux right now but in addition to these players I have Tomlinson, Westbrook, Chambers, and Driver. Pretty good solid team with the questions above. Thanks in advance for your insight.
