I’ve never had any guinea pigs so I can’t provide any personal insight, but it seems like you've already received some good personal insights!

When researching for caring for guinea pigs, I believe that the housing, food (I think having 2 bowls each is a good idea!) and toys that you have already listed are in agreement with my research, so you’re probably on the right track!

You might want to consider getting your guinea pigs used to handling before you need to groom or cut their nails. I do remember reading somewhere that grooming can also be good for bonding and getting used to being handled.

As for handling, you might also want to consider letting them getting used to you and being handled by you as soon as you can, providing they don’t show signs of stress. You might find this and this guides to looking after guinea pigs helpful. We also have an article on keeping guinea pigs too.

Hope this helps a little
