hifi engine

Newbie needs advice

Hi everyone, I'm new here and I don't know much about HiFi.

I have
-Cambridge audio A1mk3 se integrated amp
-CD5 CD player with Celestion F30 floorstanders wired to the A1

...and have just inherited my Dads old
-JVC JR-S81M stereo receiver (amp?)
-Goldring Lenco GL75 turntable
-two pairs of Videoton MiniMax2 D132E shelf speakers.

I was wondering how best to utilise them and if 2amps can be joined in the same system???

Ultimately I would like to get some Apple Airport Expresses to stream my music around the house from my iMac.

Any advice or opinions would be greatly appreciated.

Many thanks in advance Andy
