Welcome to cutting the kits loose, you'll love the freedom!
As you just experienced, many kit instructions are bound to cause more problems than preventing them. Really, how hard is it to re-hydrate yeast properly? The better more up-to-date kits actually do include instructions on re-hydration. Also, the whole secondary after x (yeah, single digits) days is so unnecessary and usually plain wrong. Placing the fermentor in a "warm place" is usually not good for a beer's flavor either.
If you need to repitch at later time, which you probably and hopefully don't need to do, it should be done with a large starter at high krausen. Otherwise repitching yeast will have no effect. What you do need to watch out for is that your beer doesn't spoil sitting idle for a week. So keep a close eye on the progress and if it doesn't do anything after a day, or 2 at the most, confirmed with a hydrometer sample, a properly re-hydrated repitch of S-33 will be the best and quickest to do.
S-33 is a high alcohol tolerant yeast and although not the prime choice for a Triple, it will make fine beer and should attenuate well. You could feed the fermentor some sugar (~1 pound) after the primary fermentation has come to an end to boost alcohol and dry it out a bit. Extract beers tend to stay a bit sweet (higher FG than expected). At the end of the primary fermentation (and after the extra sugar has been consumed) you can raise the temp slowly to 70-75 and leave it there for 2-3 weeks to finish out.
Just keep your sanitation standards high when tinkering with beer, which you should keep to an absolute minimum anyway, and watch out for unintended oxidation. Don't rack if there is no good reason for it.
