Concerning hosting sites

[JunkyPic]

I'm sure there are a lot of experienced server admins on this site, and me, as a newbie wanted to ask you guys before I go spending money on a hosting site.I want to host a Tekkit server, with little to no plugins(the only one that I would like to install is Essentials, other than that, nothing), pure SMP. So here are my questions:

1. What should I look for to begin with in a host? RAM over CPU? Bandwidth? Internet Speed offered?

2. How much RAM is recommended per player?

3. What should I avoid in a hosting site?

4. What is the minimum recommended server configuration for a, let's say, 15 people server?

5. Could anybody suggest a site that they have had the pleasure of working with in the past which left a good impression on them?

6. Given that in the future I'd want to install other plugins, which ones should I avoid?

Thank you for your time.
