Your most relevant category pages will takeover positions of products, but this won't change your traffic in any way.
Hmm... I am interested in why you say this. Could you elaborate further?
Between Panda refreshes/update when you take some position for some KW with page A and then you noindex it, some other page from your website will take this position even if it is not as relevant a page A.
New page will be gone with next Panda update/refresh.
