Congratulations on your new pool!!! Chlorine and Acid are the basics, and likely all you will need for a while. Nearly all of these products are the same wherever you purchase them. Check the labels to be sure of actual content. Test the pool regularly, and about every 2-3 months take a water sample in to Leslie's for a more thorough check. If you run into problems, this site is a great resource on how to handle algae, phosphates, TDS, CYA, etc., which likely won't be an issue for you in the near future, if you keep things in balance.
Good Luck, Happy Swimming!
