I have done many searches and read many topics but still am very confused,so will quickly explain the situation and I would be grateful of any advice or help.

I own a 2005 widetrack STi Standard with NO PPP.....I'm wishing to increase the power,so want to sort exhaust,filter,plugs,walbro,remap.

So I have gone and brought a full WR1 Prodrive System,believing this system is going to be an upgrade to my current system,less restrictive and match very well with my other plans.

Is this correct?how many cats do I currently have and how many will new system have?

Yes that is correct. The wr1 will have a single sportcat. Your car will have two normal cats, 1 in downpipe and another directly after that
