Welcome to CT @Quebert...
A good first step is developing your palate.
When I shop I taste everything I can get to without actually opening the package (altho the market where I do the majority of the shopping will open something up if I ask and it is not hugely expensive).
If it is a large piece of whatever I will ask the produce guy to slice a piece off (even I have my limits and would not dream of biting into something and then putting it back lol) and he is more than happy to do it.
In fact he carries a pocket knife for just this reason.
He is also a great brand ambassador for his store pointing out new varieties he thinks I may like.
Same with your cheese market and bakery shops.
Helps me figure out if some new exotic ingredient (usually expensive) appeals to my taste buds before making a new dish.
One last thing (and just IMO) don't buy sets of things (well except for tableware)...
Put your kitchen equipment together piece by piece choosing the size and weight that works best for you and your needs.
Those cookware sets (and cutlery blocks full of "matching" knives) always include at least 2 pieces you will never use....if you need a block to keep your sharps in then buy one or even better treat yourself and have one made (FYI if it is a block you want store the knifes with the sharp edge UP to keep the edge longer).
Personally I have a drawer tricked out to spec (lined with soft foam and velvet) and keep everything locked up (have lots of kids around and don't want any tiny humans deciding to cook while I am not looking).
So have fun reading and don't forget there are no stupid questions (actually there are but most of us have good manners and will answer politely anyway lol).
OBTW... check out the knife threads.
Hugely informative and those guys know their stuff.
