wp proof for ILR (wp + Tier 1 + Tier 1 extn case)

I am applying for ILR in jan 2012 at Croydon.

I entered UK on 28th Jan 2007( 1 yr wp), Got wp extended in jan 2008(1 yr extn), Got Tier 1 in April 2008( 3 yrs),got Tier 1 extended in april 2011(2 yrs).

changed employer in jan 2009.

questions:

1. Am I Ok to apply for ILR any time in Jan.

2. I only have "UK entry clearance" stamp in my passport for first work permit, dont have any other letter. Will this be OK.

I do however have wp extension letter ( as well as visa in passport) and have other home office letters for tier 1.

I have all 5 years p60s and sal slips, have p45 from 1st employer.

is this sufficient proof of my work permits and work before my tier 1?

Thanks in advance.

You will be fine to apply anytime in January, from 31th December in fact.
