One other major thing that beginners don't realise is that a lot of the actual tone from a good player comes from the guitarists technique. A really good guitarist can make a poor set up sound impressive. When you get a great guitarist with a great setup then you get the Vai, Satch, Petrucci or Slash sound. It doesn't matter how cool your set up is once you're a beginner, it won't sound professional untill you develop good technique (not just alternate picking, legatto and sweep picking... more like stylistic techniques such as vibrato, sliding, palm muting on/off during phrasing, pinch harmonics and other 'hands on guitar' tone shaping stuff. It's a lot to expect when you start out to be able to match the sound of one of your favourite players.
What you want to achieve now is a 'basic' core sound that you are happy with, forget trying to get the exact sound you hear on an album (consider the cost of that sound in the first place - say €2000 for the guitar and about €50,000 for the engineer and studio time.... and that's just for starters!).
If you are going to change anything in your setup I would suggest changing the pickups - Ibanez are great guitars even on the low end. Stick in a pair of Dimarzio Evolutions and you will have a great beginners guitar - it's up to you then to experiment with the rest of your gear, ask questions here and use the search function in the forum to look up tone advice. Hope that helps!!
