Although having a vacuum sealer is useful, you don't really need it for sous vide as there is the water immersion method with just a ziplock bag.
Check out the Anova site for a bunch of info and recipes in English.

My advice is to keep it simple when you start out. Once your passion upgrades, perhaps consider culturing your own sourdough starter for homemade sourdough bread. It still keeps within a simple budget but requires a bit of time.
Also consider getting a good kitchen knife and learn how to use a sharpening stone. A chef's knife is the one tool you will probably use the most often in a kitchen when preparing food.

If you have a higher budget, you might explore gourmet ingredients and fancy kitchen tools later on.
Regarding gourmet ingredients, don't use truffle oil as most are scented with synthetic material and not really made from real truffles.

I'm not a professional chef but just an amateur home cook with a passion for learning about good food and its preparation.
I do own some very nice chef knives. One of my newest acquisitions from this February is a 225mm Gyuto in RWL-34 steel and Redwood Lace Burl.
Of course, such a handmade knife is much more expensive than most production knives you might find at your local department store. It would be similar to comparing a slate and shell go set from Kurokigoishi with a glass stone go set from Korea.
