It's okay. Maybe not ideal, but better than nothing.

Not if this is only your starting point.

I recommend it. You will definitely learn networking, and most Cisco specific things can be found elsewhere under a different name.

Cisco is trash, get a book(pirate if needed) & gear or GNS3 and practise with it.
You can use packetracer too if it's just CCNA

I don't have gear. Just one shitty chromebook with linux.

It's an okay starting point. Depending on the course though, it may be not really 'entry-level' when you go in... so you might want to be familiar with basic stuff before hand.

No, you won't screw yourself over by learning only Cisco stuff to start out with, I don't think.
You just gotta make sure you also continue your education and learn other popular (and obscure at times) brand's stuff.

Recently I had to read up on MikroTik's RouterOS. These cheap ass routers have some serious functionality and are pretty reliable from my experience, but they don't act like Cisco's stuff so when we had to put in some of those, it took me about two days to really get the hang of their stuff. My original education (formally) was Cisco classes, and what I learned there definitely wasn't 'wasted' on this project, but I did have to learn some new things.
