If possible, find out what the structure will be. How much play it allows should be considered when deciding whether to enter, and if you do, in the play as well. Assuming you're going to play tight, the slower the structure, the better it fits you.
Also, don't go in thinking everyone will be levels better than you. It's more likely that your table will have a mix of players who will range in ability from some you're very comfortable playing against to others who are clearly well above where you're at.
As for using your tight image to 3- and 4-bet, try to focus on doing so against the people who are looser. If you happen to get down to a smallish stack, look for opportunities to re-steal shove, preferably against the loose players as well, while you still have enough chips to provide reasonable fold equity.
