41st lv DM
What other things should a super noob like me not forget? Im super freaking nervous. Failure is not an option, resistance is futile. Please halp meh.

Failure may not be an option, but it's an absolute certainty. Especially for a 1st time DM.
But don't worry, that's completely normal. It's part of the learning curve. The more you DM though the easier & better it will become.
So it looks like you're playing PF.
Step 1: Limit your 1st game to the Core rulebook + Bestiary 1.
That's it, that's all. No other books, nothing pulled from on-line, no making up your own classes/spells/monsters/etc (either by yourself or your players).
This is because you're all essentially starting from scratch.
Step 2: READ the core rulebook. Particularly the chapters on how to create characters & combat. And then read it a few more times....
Read through the Bestiary 1, concentrating on weaker monsters. Sure, dragons etc are cool & interesting. But goblins & zombies are your training wheels.

Step 3: Write up a short adventure using monsters that have about 1 HD each - goblins, kobolds, etc. You're looking to provide about 25% of the total XP the party needs to reach lv2. And about 1 to 1.5 monsters per player, per encounter area. So if you've got 4 players, about 5 or 6 goblins or whatever at a time.
You need enough monsters so that both you & the players each get a few turns of action so that you can see how the rules work.
If you can provide a paragraph of "story" for this? So much the better. Ex: The goblins have raided the shipment of Dwarven ale & the PCs are sent to exact vengeance (and bring back the ale!). The reward is _____.
Step 4: You say that you don't want your lack of experience doing this to slow down play. This is NOT possible. At least if you're trying to learn the rules. Do not worry about wether or not things bog down while you or the players look something up in the book. If you need to look it up, look it up.
Both you & the players are learning this stuff together.
