Skye's ducks is a really good post. There is SO much to taking care of rabbits that it's difficult to get it all in one post here. So I'll just give you a couple of good links for the most part. But I do want to emphasise one thing; do not keep rabbits with Guinea pigs.
Will there be people who say "my Guinea and rabbit lived just fine together"? Yes. In fact I had two live happily together for a couple of years. But we also lost three guineas to over rambunctious rabbit play/hierarchy displays. Guineas and rabbits have different food requirements, different space requirements, communicate and interact differently, and even a small lop is big enough to accidentally kill a Guinea with a simple dominance hump. It is far, far better to keep rabbits, (which live in small social groups in the wild) with other rabbits; http://wabbitwiki.com/wiki/Relationships_with_rabbits#Guinea_pig
Number one best place in the whole internet for rabbit care advice is the rabbit sub reddit. Any and all questions about rabbit care will be answered by one of the long standing, highly knowledgeable users. The sidebar also has lots of links to the rabbit wiki these folks have put together and other sources. It's utterly comprehensive; https://www.reddit.com/r/Rabbits/
I linked to the wiki above, but this is the "beginners" care page; http://wabbitwiki.com/wiki/Getting_started_with_a_rabbit
In the US, the biggest rabbit org is the house rabbit society; https://rabbit.org/category/care/
Rabbits make amazing pets, but only if their needs are met correctly. I have three house rabbits and they make me laugh every single day with their antics. I've kept rabbits, not including when I was a kid, for six or seven years (my oldest is about 9), and I can't imagine being without them. But they are hard, hard work, way more than my chickens, and I can't even begin to add up their vet bills! One single ear infection amounted to £2000! I have them all insured though, so I only paid £55...
