You don't need all of those tips (I don't really like using auto-mixing for herbs), however what I think is handy is the fact you recover stamina faster while prone or in cover. What this means is that if you are using a lot of quick-shots and melee, you'll want to take advantage of this after your next dodge and use your gun while prone instead of immediately getting up.
If you need this thread, then consider jumping into Mercenaries before starting any of the campaigns. Give it a few rounds, or maybe until you score well. At the same time you'll be collecting skill points, which I think makes the game feel better (damage up and aim steadiness).
The game is certainly better than many people seem to be giving it credit for (which is to say people think it is the worst thing ever). The combat system is nicely layered and works out to be something original, an advancement even (especially when considering the great enemies hand and hand). Sliding, rolling, and shooting while prone are all fantastic additions on the level of RE4's addition of hybrid shooting and melee to the series. I get a lot of satisfaction out of rolling out of the way of attacks and then retaliating while prone, all of this one smooth movement. Can't imagine RE without it now (and I don't feel like it is superfluous, on Professional anyway, which is the only way to play really). If you are wondering about comparisons to Vanquish, well the way you would shoot out of a dodge (ideally for activating slow-mo) isn't unlike RE6's evasive prone shooting.
Worst thing about the combat system is the camera, which is not an insurmountable thing to get accustomed to. Aside from that, I wish cover was better integrated (doesn't mesh well with the rest of the combat system, doesn't build on melee or dodging, Jake's charge is only somewhat an exception) and that the relationship between gunfire and dodges was as smooth as dodging melee attacks (to be fair it is not like Vanquish or Max Payne figured this out either, hence the reliance on slow-mo). There are certainly moments in this game where I wish it had a Riot Shield weapon (thanks for putting that into my head Binary Domain).
