If your kit is an extract kit then the directions should be fairly straight forward in the kit. One thing to note is when they say to add your hops at 60 or 15 minutes for example, this means time from the end of the boil. Since a typical boil is 60 minutes, the 60 minute hop goes in right away and the 15 minute hop goes in 45 minutes later.
Make sure you sanitize very well. There's a difference between being clean and being sanitized. Everything that touches the cooled beer after the boil will need to be sanitized to prevent issues during and after fermentation.
After you pitch your yeast, make sure the fermenter is in a temperature stable environment within the yeasts recommended range. I feel like 65 F is a good target temp for most ale yeast but check the package. To further keep the temp stable, placing the fermenter in a water bath is good to act as a heat sink to pull away excess heat and keep the beer temp stable.
Place the fermenter somewhere you don't mind getting dirty just in case something happens like overflow or clogged airlock. Chances are that won't happen if your fermenter is 6+ gallons capacity.
I recommend giving fermentation 3 weeks minimum for all beers before bottling. Transferring to a secondary is not necessary unless you're aging it a LONG time or adding fruit or something.
If you have a bottling bucket and auto siphon, practice the transfer from your fermenter to your bottling bucket with water to get your method down before trying it with beer. You get one shot and aerating it with splashing and bubbles isn't good at that stage.
Know how much priming sugar is needed for the beer style and dissolve that in 1-2 cups of water and boil at least a few minutes. Put that in the bottling bucket first after cooled and rack the beer on top. Gently stir with a sanitized spoon if necessary. Have at least 50 sanitized bottles and caps ready to go before starting bottling.
That's all I can think of. Good luck! It will be beer and you will learn how you do things in a way that works for you. I'm just giving recommendations based on what works for me.
