Ok, so I did a bit more reading about set and rep ranges and I know the optimal range for both strength and size is 5-10 reps if you're looking for strength and size.
It always says that in theory, but as I point out from time to time, my best size and strength gains came on low reps, usually 1-3 reps per set for compound lifts. Years ago, I took my deadlift from 455 to 545 lbs. without ever going above 5 reps in a set, many times going into the gym and working up to a few heavy singles and calling it a day. Same with my squat, it was a lot of heavy low-rep work that made me stronger, higher rep stuff just kicked my endurance up a notch but that was it. The usual "X reps is best for X results" has a lot of factors to consider for what will work best for each person, as some will see better results on low rep, some on higher rep.

I also read that often times sets over 3 can burn most people out. And as I recall on my 5x5 I did get over over trained.
Like Chewy said, intensity will be the greatest factor in this. If you're, say, squatting sets of 5 at 90% of your 1RM, it's going to wear you out a lot more quickly than if you're doing that volume at 75% of your 1RM. If the last rep on each set is killing you to complete, then you're certainly giving it 100% intensity, but if you're training sets of 5 and feel you could have knocked out 6-8 reps each time, then you're using far less than full intensity on your sets. I think that's what Chewy was also getting at, the intensity factor will determine a lot more about where you're going to feel "burned out", particularly when you're giving it 100% on each set vs. working with weights you can make every set with easily enough.
Not to mention, some people just aren't great at adapting to higher rep stuff without a lot of work, even if the weights aren't at a high percentage of 1RM. Me, I'm primarily built for low-rep stuff for anything 85% of my max or above, but drop the weight slightly and I can rep out some lifts all day long and barely get fatigued (such as with upper back stuff, where I have great endurance with moderate weights, while my legs/lower back are taxed quickly even with lighter weights and higher reps). Even with upper back work, it took me almost 6 months of focusing on working to build endurance to handle more volume before I adapted, it was a long road to get there.

I'm also going to do something utterly stupid and completely eliminate cardio on my 5 lifting days.
Sounds to me like you're making the better decision here, not stupid at all. Cardio isn't going to help you gain mass, so get rid of it for a while and see how things work out. You can always add it back in later if you want, but for me, the less cardio, the better the gains.

My last question is how much rest between sets? I was doing 2 minutes for the longest while. Would switching to 3 be beneficial? Or does it not matter?
Rest periods are very much a personal preference more than anything else. If I'm really winded after a hard set, I may need 3-4 minutes of rest, such as after going all-out with squats. At the same time, sometimes I can get away with 1 minute of rest, it all depends on how I feel (I don't really time rest periods often, I usually just guess when it's about 2 minutes and repeat as necessary). The less rest you take, the more it's going to kick you in the butt on endurance and you might find that you're sucking wind before you are done with your sets, so if you want to build your endurance up, cut the rest periods. However, I found that my best gains came with making sure I was plenty rested for every set, so don't feel that you MUST race back to lift after 2 minutes exactly, it's not a magic number. If you feel that you're not ready after 2 minutes, give it a bit more time, and see how it impacts your lifting. Experiment, experiment, experiment, because the more you play around with to learn how your body responds, the more progress you'll make in time!
