Whoa!!!!!!!!!! Hold on a minute!!!!!!!! You wouldn't want to be using all
of that list of ingredients in one 5 (US) gallon/19 litre brew
Try something like this
Your Black Rock, miner's stout kit can (1.70kg/3.75lbs)
+ 1.5 kg/3.3 lbs of liquid pale malt extract
+ 1 kg/2.2lbs dark brown sugar
21g / 3/4 Oz of Nugget at start of a 40 minute boil
14g / 1/2 Oz of Cascade at 10 minutes before flame out
This should be quite well balanced, as in not ridiculously hoppy and plenty malty.
Use about a couple of lbs of the liquid malt extract, mixed thoroughly with hot water whilst off the flame, you could also put the sugar in too, bring to a boil then make your (for example 40 minute) Bittering hop addition (3/4 Oz nugget @ 40 minutes), keep a slow rolling boil for 30 minutes then do your flavour/aroma hop addition (1/2 Oz Cascade @ 10 minutes). Boil for another 10 minutes then turn of the heat. Add the remainder of your liquid malt and the contents of your kit can. Cool, add to fermenter, aerate as vigorously as possible, top up to 19 litres total, pitch your yeast.
You'll probably be best making sure you have a decent yeast, and enough of it. Safale S-04 for example. The yeast that's under the lid of your Miner's stout kit can might not be in the best condition and there's only 5g, (or is it 7.5g? I'm not sure) of it so that would be far too little to ferment a batch of this size and volume of fermentables. My calculations sahow this coming out at somewhere near 6.8% ABV, an OG of 1.070 and an FG of 1.019. So even 1 sachet of S-04 might not
be up to the task of carbonating the brew after fermentation, or being able to fully ferment this batch. Maybe someone else might be more knowledgeable and able to advise.
Here's another link
that you might find valuable and insightful. I highly recommend you have, at least, a quick scan, better even a proper read, through that as it will be helpful for you.

Oh, and by the way, just so you know. The more fermentables you use and higher ABV you attain, the longer it'll take to condition and carb.
