Just one adjustment I'd suggest to #2: sparring can be about winning, but it shouldn't always be about winning. Sometimes, the best benefit is when the other guy is using his best stuff to stop your best stuff, and vice-versa.I agree with most of what has been said already. But I did have some additional things to consider.
1. Study the rules you are using in your sparring. One of the important things they will tell you is: What you are not practicing. This is important. If you are doing stand up striking, you are not practicing take down defense and you are not practicing ground fighting. If you are doing Judo style randori, you are not practicing punches and kicks. Some places that do stand up striking, don't let you hit to the head, which means you are not practicing targeting the head, nor are you practicing protecting your head. Once you learn what you are not practicing in your form of sparring, you at least know the holes you need to work on. You can change your sparring rules, find outside sparring opportunities, work on drills... Further, when you find something that works for you in sparring, you need to find out if it works because of the rules. If you are not allowed to strike to the head... and you find a way to consistently land a combo on the other guys, you need to figure out if that same combo works when the other guy can snap your head back with a jab. Are you only able to get that choke, when the other guy has no gi on? Are you only able to break out of the clinch because the other guy is not allowed to use a double leg take down? This does not mean your sparring is bad. This means you need to understand what your sparring actually is.
2. This was already stated here before, but I want to reiterate. Sparring is not about winning. Sparring is about practice and learning. When it is about winning, you start relying only on your go to, tried and true techniques... because you want to win. But, if you can keep it about learning and practice... then you are free to work on the things you are not so good at, so that they become better. If a drill is taught that day before sparring... use that drill in your sparring. If the other guy gets you with something, try to get him with it. It might not work (probably won't) but you will get to see how they defend it, and you will have something new to work on... eventually you may get it. If you are bad at a certain aspect, put your self in a position to work on that. (maybe you have a hard time getting out of side control... get yourself in a position to practice your escapes over and over again)
3. What else can you work on while sparring? Its more than just the techniques. If you are in a ring... can you keep your opponent in the corner? Can you pick which corner? If there are multiple pairs sparring at the same time, can you be aware of where everyone else is on the floor? Are you the one bumping into the other pair or can you make it so that your partner is the one bumping into everyone else? Can you keep yourself closer to the weapons on the wall than your opponent? There are a lot of things you can work on while sparring, beyond just: Can I land this punch?
