No problem on being ambitious. My second beer was a Belgian strong beer which is similar to what you are brewing. I found the quad you are brewing better tasting. The Belgian strong had to sit for close to 2 years for it to taste better. Good choice on the northy by you.
The temperature of the wort will run higher than room temperature because the reaction catalyzed by the yeast is exothermic so wort runs 5-10 degrees hotter than room temp. I once measured 15 degrees delta T but not sure of that measurement as I was not using same measuring device for wort temp and air temp. With the yeast you are using, you should be fine as the top end is 78F.
Let the stir bar slide down gently to the bottom of your flask so as not to break the glass. Don't let the stir bar fall in the fermenter like I did....blush. I am going to buy the stir bar removal tool next time I have to buy extra to get free shipping. https://www.northernbrewer.com/products/northern-brewer-yeast-stir-bar-removal-tool. You may already have one if you bought the maelstrom.
Harvest the yeast to allow you to save some $$$.
