What type of hosting do you have?

I am currently on a shared reseller account and was wondering when (and why) I should start looking at a VPS or Dedicated option.

I have no server experience really and am very happy using my server support.

Can you tell us a little about your site and what it utilizes. It is a not an easy answer because it depends what kind of host you are using.

IE, ie one host has 3 times as many users per server as another. So using that host you would slow down faster. It is really related to what you currently use in your shared account and how much power your host allocates.

Now if you trust your host, they are paying attention and they know what they are doing, they should be able to tell you at what you need to switch or look at other solutions. Because if a host isn't telling you this and you are slowing down then they are not paying attention to their servers. A slow site is NOT normal unless there is a reason.
