Probably too late now, but S-05 and WLP001 are essentially the same yeast (chico strain). I prefer the S-05 because I get twice as many cells in an easier to care for longer lasting package at half the price. But YMMV.
As for whether or not you can just pitch the vial with no starter, read what jmo88 wrote above. Unless you tell us the OG and how fresh the yeast is, theres no way for us to know if it's a sufficient cell count for the beer or not.
