Welcome.
There are a few threads on here about different methods for long cooks. Tried snake once but didn't work for me. I prefer minion. Could be down to the shape and size of the WSM I have but I find minion just works for me.
Also a lot of threads on different types of coal. I have used lump a couple of times for 4hr cooks but find temp regulation harder than with briquettes. As a result I've not really persevered with lump on low and slow.
I have used a lot of different briquettes and found Aussie Heat Beads to be the best of the bunch. No acrid unnatural smells and keep a good long steady burn. Got 14 hour cook from one basket a couple weeks back and reckon I would have had a few more hours on top if I'd needed.
The thing is to read up, listen to advice and try stuff you like the sound of. You'll end up working out what works best for you and your smoker.
Most importantly, enjoy the experimenting....let the fun begin
