First off I'd like to say that I love this site.  I have been researching components for about a week now, and these forums have been extremely helpful.

I am building an entry level system to try and breathe new life into a vinyl collection I inherited a year ago when my Father passed away.  Up until recently, I didn't have a whole lot of spare cash to sink into it, but now I am looking to build a simple, compact system to play his records in my new apartment.  Based on research / listening to different setups at the local hi-fi store, I've decided on the following components:

TT:  Pro-Ject Debut Carbon

Integrated Amp/Pre-amp Receiver:  Harman Kardon HK 3490 120 watt

Speakers:  B&W 686's or Polk RTI A1's (haven't decided yet, loved both at the hi-fi store)

I have seen a few other posters planning on a similar setup, so I assume this should be an O.K entry level system with a clear upgrade path.  

My question(s) is:

1.  Do I need anything else, or will unpacking the three components listed above give me all the parts necessary to plug and play?

2.  I have never connected a speaker wire to a receiver before, and frankly I'm not sure if either of the speakers I've listed will come with wire included.  This is easy enough to look up in the user manual online, but assuming they do...is the included wire sufficient for the components listed, or should I buy new / better wire?  What would you recommend if I need to purchase new?

3.  Will the HK 3490 provide adequate amplification, or would I need a dedicated amp / phono stage?

Any other feedback you can provide to a complete and utter audio newbie would be appreciated.

Thanks in advance.
