I Am Such A Noob…

So, I am BRAND new to WordPress, and, although I tend to catch on to new things quickly, I seem to need a bit of a push in the right direction when it comes to all of this. I’m just going to lay out a bunch of questions, and if you all can find me some answers, then that would be amazing! And if you’re really into it, feel free to throw some tips that seem useful to a WordPress noob like me out here. Thanks ahead of time!

1. Is it possible to change the font of the site title/tagline? If so, how?
2. How do I get rid of the auto ‘Home’ tab? Is there a way to do it without having to to go into the zipfile and change it? Because that doesn’t seem to be working.
3. Does anyone know off the tops of their heads how to connect Paypal to my site? I’m planning on turning my blog into a literary editing business… so, I’m going to need to have Paypal for my customers to… well… pay!
4. Are there any super cool plug ins you guys might be recommending?
5. How do I disable comments for certain pages (but not necessarily ALL pages)?

I guess that’s it for now… like I said, I’m a noob when it comes to WordPress, and I could use some help!
(: Thanks!
