Retrofit MFSW

My second post as a new member and Octavia owner. Buying a used car means you can't pick the options it comes with, although having VCDS you can often retrofit them, especially with the help of members of forums like this.  The car is an automatic, but currently doesn't have the paddles, I'm not fussed either way whether the new wheel has them of not, I never used them on any previous cars!

My question is what parts do I need? Having previously done this retrofit in an Audi A3 with paddles and an A6 without my guess would be that I need;

• A new wheel with controls, maybe an 5E0419091BQ - the current one is a 3 spoke so I want to be able to reuse the airbag
• A new slip ring? On my A6 the slip ring for the standard wheel needed replacing. Current ring is 5Q0953549E
• New airbag loom that adds the steering wheel switches on for the yellow connector, I believe part 5E0971584A
• I've seen BCM mentioned in other posts about MFSW retrofit and don't know whether I'll need a replacement. My current one is 5Q0937084AL, I'm hoping I don't!

Any other parts? Once I've fitted them all it's just some coding I guess? Any pointers for that would be appreciated.

Thanks in advance.
