Welcome aboard friend! I'm maybe closer to a novice myself as I've been completely immersed in this hobby for only a little over two years and counting.
To be clear, are you saying that you have about $1-1.5K to spend each for the pieces you're considering? Roughly, $3-4.5K total? For your first foray into this all-consuming hobby I'd say that's a pretty healthy budget. There's an awful lot you can get for that kind of money, especially if every component is purchased used.
Before buying anything you should go out and listen to as much as you can in order to form opinions of what you do and don't like, because it's all about personal tastes [personally, I don't find B&W to be sweet sounding]. I started with solid state integrateds matched with monitors, and eventually moved to a tube preamp with a solid state amp. As you listen and learn, your tastes will also evolve and your opinions will change too, much as mine have. If you become as crazy as the rest of us, you'll most likely end up buying and selling all kinds of stuff, more than you ever imagined you would.
You'll find varying opinions about whether you should build a system around your speakers, or start with the amp first. Frankly, I don't know which is the best route. And that's why I suggest you try and find local high-end dealers or friends that have equipment you can listen to. If something really moves you during an audition, then maybe that's where to begin your system. Also, read magazines and online reviews, but remember not to take what's written as the holy truth, because they are in themselves only opinions. See what people like and what they're combining them with, and if you have the chance to confirm what you've read through a listening session all the better.
As for recommending a specific product, a lot of that depends on how you like your music presented. You say you like jazz, opera and pop, but do you prefer it to thunder down on you, or flow gently over you? So, to start the ball rolling, I'll put forth some system ideas within your budget and see what fellow Audiogoners have to add.
If buying a new CD player a good place to start might be with the Rega Planet 2000, or if used a Theta Miles. Also, see what you can dig up on the new Jolida CD player.
Something that has me really intrigued is the Rogue Tempest tube integrated amp at about $1400 used. I've tried the Simaudio Moon I-5 and Electrocompaniet ECI-3 integrateds and felt they lacked the warmth I like, and with your hardwood floors they may exhibit a lean character.
With speakers it gets a bit trickier because you must decide whether you want a floorstander, a monitor on stands, or a monitor with a subwoofer. Both have their advantages, and then there's the whole issue of proper setup. For floorstanders look into the Vandersteen 2s, Meadowlark Kestrels, Soliloquy 5.3, and ProAc Response 1.5. For monitors check out the ProAc Response 1SC, Sonus Faber Concerto, Vienna Acoustic Haydn, and Totem Model 1. And for subs, a real favorite on Audiogon is the REL Storm and Strata, but don't forget the ACI Titans.
Also, Don't forget about cables!
Well, I hope I've helped more than confused you. I know it's tough to start with so much to learn and experience, but remember, this is fun! It's all about the journey! Enjoy!
