I already have some of the initial dialog set up for right after the first fight.
Be careful not to paint yourself into a plot corner. I personally find it best to make a short list of simple ideas I want to share at certain points, depending on the outcome of encounters and the decisions and direction of the PCs, then I decide in the moment if it is appropriate to share them based on the actual circumstances. Too often it is easy to get caught up in predicting what the PCs will do and finding the options you suspected and the prep work done doesn't fit what happens at the table, then it can appear that the PCs are being shoehorned or railroaded. Try to design in a way that leaves as many options to you as possible.
