No, you've got everything you'll need. A head gasket replacement isn't a job that requires lots of specialist equipment. It's mainly a set of wrenches (including a torque wrench) and something to scrape the old gasket off. But it's a long and tedious job. And I can't stress that last bit enough, especially if it's the first time you do it.
If you want to make the job as smooth as possible, I would suggest taking the engine out of the car completely so that you have lots of elbow room. but that's a big job in itself. For that you'll need a winch and a crane (or whatever the thing is called in English). I remember getting extremely annoyed at the fact that I couldn't adjust the second waste-gate actuator nut on my turbo because there is no angle at which you could get at it even with the shortest #9 wrench on the market. Instead of it being a 2 minute job, I spent a good hour on it and had to cut a wrench in two in the process. The alternative was to remove the entire exhaust manifold heat shield (to get to one tiny little nut!). It's unexpected difficulties like that that trip you up. But if the guy in the video can do it, so can you. Just take whatever number of hours you think it'll take and multiply by 2.5.
And next time buy a car with all the cylinders in one straight line. It cuts the time in half;)
And take 2 minutes to block each and every hose you removed. If you drop something into e.g. the pipe going to the intercooler, you're going to spend hours trying to get it out again.
