Questions from a Hi-fi virgin and a new member to the Naim family

Have been lurking the boards and must say thanks for all the information, it's been a great read.

Well I've finally gone and done it. I've bought my first hi-fi system and I'm happy to say Naim is part of it.

System as follows:

Naim Nait 5
Arcam CD72
KEF Q55.2
Chord Chrysalis interconnects
Nac A5 speaker wire

I demoed and auditioned other components and nothing came close to the above kit, and that which did cost a hell of a lot more and was seriously over my budget. I shopped around, bartered and managed to get change from £1500 on the above system. To say I was happy is a serious understatement!

Anyway after getting home and excitedly setting up my system, I started spinning discs. My questions are:

1. what's the best way to run in a system?
2. how do I get the most out of my system?
3. how do I keep my system in its best shape, and
4. any suggestions/hints/tips for in the up keep and maintenance of my system.

So far I've left my amp and cd player on since I've set the system up. I've been playing the system at various volumes from soft/moderate to around 1 o'clock on the amp. The only thing so far that I'm corncerned with is that when I connected the speakers, I found that the clip for the positive(black) doesn't extend as far into the speaker termination plug as that of the negative clip - the negative terminal fits alot more snuggly into the speaker plug. When I shifted the speakers I found the (+)plug would come out quite easily. I also put this down a little to the inflexibility of Nac A5 speaker wire.

With the Naim speaker termination plugs that connect directly to the amp are the speaker wires supposed to point down or up from the connected speaker plugs?

Anyway thanks for reading and any help/suggestions/tips/guidance will be much appreciated.

cheers
