I'm a little new to this VPS thing, and I'm not 100% sure it's going to be what I want. So I'd like to try it out before I commit to a year of service.
If I sign up to pay month-to-month and find out I love the service, can I then pay for a year and get the 10% discount, or am I locked into month-to-month if I start that way?
Just file a support ticket asking to be moved to annual billing.

Also, it's pretty simple to upgrade my linode or add another one to my account if my site takes off and I need more resources, right?
Yes.
Adding a new node is very easy. (It's just like when you create your first one...)
To upgrade your node, file a support ticket; they'll configure it and give you a button to press.
If you need to upgrade immediately, you can use the Extras page to add extra RAM, disk space or bandwidth onto your node, or you could create a new node and clone your disk images over.

Is there any difference between the different data centers other than location? Like, if I live in New York and my greatest concentration of users will be in the northeast, is there any reason not to use the Newark data center?
Atlanta blocks some ports, most notably those commonly used by IRC. Other than that, location is the only difference.
