Hmmm, looks like this may come too late for you, but I'll throw out a few thoughts anyway.
Regardless of the limit on the final hand, you still want to use the usual techniques (progressions, correlation, opposition, etc.) to put yourself in position before the final hand. At a 1 advance table, you generally want to be BR1 on the final hand. If you succeed, then the no limit bet on the final hand isn't much of a factor. You can still use the normal methods of protecting your lead, but with the lack of limits factored in.
If things don't go your way, for whatever reason, and you are not BR1, sometimes the no limit bet on the final hand can be a blessing. It makes it less likely that your opponents are completely out of reach on that final hand. For this reason, I generally play a more conservative game in the early going. Once again, you can try some of the usual strategies, but with the strength of your entire bankroll behind you. Sometimes being more than a max bet down on the second to last hand suddenly becomes a within 1/2 a bet situation on the final hand and you can take the high. Or you suddenly have enough chips to try Curt's Revenge or to bet according to the rules of 2, 4 and 5.
One property of no limit final hands that you can also consider is the tendency for players to go all-in without thinking. This is especially true of players who are behind, but is done more often than you might expect by players in the lead. This gives you the opportunity to beat these players low by holding back some chips. If players who bet before you do this, then all you need is a single chip. For players who bet after you, it will be a judgment call but, in general, on a a no limit final hand they will often bet more than usual and sometimes enough to give you an opportunity.
