ᐅ Cabinet: Which parts are needed for installing a refrigerator?

Hello IKEA fans,
I have the following problem – I am 72 years old and no longer drive, so I don’t have the opportunity to go to IKEA either alone or with someone else. The nearest IKEA is about 50 km (30 miles) away.

Now to the point:
I want to buy the 203.421.73 Förkyld built-in refrigerator and the matching METOD cabinet tall unit 60x50x140 cm (24x20x55 inches). Everything is clear so far.

Now the problem – I would like to know what I need for this or what is included with the cabinet.
Do I need ventilation grilles, feet, hinges? Is there even a suitable door for it (my kitchen doors are light beech – ÄDEL example no. 101.413.11)? Rails? How do you attach the door to the refrigerator door – is there a mounting set? Is there a top panel for the cabinet? Is there a baseboard, or is that left out? And so on, and so forth.

Thanks in advance for your help.
Best regards, Uwe
