と is used to show exhaustive listing. や shows inexhaustive listing (similar to とか). そして is mostly used in sentence-initial position (a lot like でも [but]). に used to mean "and" is pretty advanced, so I wouldn't worry about that for now. Anyway, on to some examples.
私は果物はイチゴとりんごが好きです。
"As far as fruits go, I like only strawberries and apples."
Here と is used, and it shows exhaustive listing, so that strawberries and apples are the only things in the list of things that I like.
私は果物はイチゴやりんごが好きです。
"As for fruits, I like strawberries, apples, and others."
Here や is used, and it shows inexhaustive listing, so that strawberries and apples are listed among other things that aren't explicitly stated. や can be replaced by とか here without a change in meaning.
私はイチゴが好きです。そしてりんごが好きです。
"I like strawberries. And I like apples."
Here we have two different sentences, so そして is used.
Also, I believe そして can be used at the end of a long list of nouns with a pause. An example would be something like 私が食べたのはイチゴ、りんご、魚、ビーフ、とこ焼き、そして桃です。 However, I believe the use of そして here has a somewhat narrative and literary feel to it, so I would advise against using it like this until you know exactly how to use it.

Leave off the 下さい here, or use を and leave out the 欲しい. 下さい is used alone to mean "please give me" or with the -て form of verbs to mean "please [verb]." 欲しい is an adjective, so it doesn't take 下さい.
