i think The La's carries the Britpop tradition a bit more than Stone Roses or Happy Mondays, though i have to agree The Stone Roses is a better album than The La's. however, if we're talking about the official birth of modern Britpop, fingers point to two albums from 1993... one hugely successful and one a commercial flop, but both highly influential to the genre:
Suede's self titled debut and Blur's sophomore
Modern Life is Rubbish.
in the early 90's, the UK went through a couple of music scenes that didn't really identify with. Madchester was great at the time but then The Stone Roses and Happy Mondays self-disintegrated... Charlatans and James evolved into more Britpop-ish music, and Inspiral Carpets disbanded shortly afterwards. Shoegazing was deemed boring by the press (it wasn't boring but much of the artists weren't entirely interesting with their Public Image), a few Shoegazing bands evolved into Britpop anyway, most noticably The Boo Radleys and Lush; and American Grunge was something to fill the gap.
by the time Suede was named "The Best Band in the UK" when they have not released a single note of music and Blur made a drastic reinvention just after one album, Britpop had arrived. everything just started rolling from there.
as for the top 10 essential Britpop albums, i'll take these (i'm doing this as i go along so i might unintentionally leave out some stuff, LOL)
Suede - Suede
Oasis - Definitely Maybe
Blur - Parklife
Elastica - Elastica
Pulp - Different Class
Supergrass - I Should Coco
Radiohead - The Bends
Boo Radleys - Wake Up!
Gene - Olympian
Manic Street Preachers - Everything Must Go
i've also wrote this in my blog on the anniversary of the "Blur vs. Oasis" rivalry for the top of the UK singles charts, if anyone's interested in reading it.

oh, and that NME special edition is great... i just might have to pick up a copy before they sell out. another great special edition i can't put down was the Synth-pop Special Edition from Mojo earlier this summer.
