I took a look at your brooder setup on your web page. I would suggest you remove the red heat lamp as you already have the most excellent brooder plate in there and they will appreciate not cooking with the additional heat of the lamp. The most important thing chicks need other than food, water and heat is fresh clean air and dry bedding.
You will also want screen material to clip over the top of the brooder as they will be flying out of there at about 7-10 days old.
The brooder is also very small. How many babies are you getting? They will out grow that space very quickly.
Do you already have your coop and run built? If so, I also strongly suggest you move them out to the the coop at around 2 weeks old with their brooder plate. They will do much better out there.
If you don't already have it, get a bottle of Corid, a small bottle of Poultry Nutri-drench, some Save-A-Chick or other chick electrolytes and a bag of chick grit. I like to give my chicks a plug of sod from the ground that they will live on when they are about three days old. This early controlled exposure helps them build up their immunity.
Good luck with the new chicks!
