First, welcome to the hobby! You are right to pick the brains of those like myself who have learned the hard way.
An amplifier will upgrade all sources including the CD, so I would do it first.
Also, quality used CD players can often be had cheap on the used market. A new, low production CD player is not a good investment.
Consider a used older, name brand (like Conrad/johnson or Quad), 75-100 watt or so power amp, instead of the receiver. A two dollar volume control from Radio Shack will will outperform anything you can afford as a pre-amp. If you do not know anyone who can solder, get back here for instruction.
best wishes
