disolitude is way more knowlegable in 3D then I am but...
Full 3D means that the tv you buy will display in 3D when you take it home.
3D ready means the tv is capible of displaying in 3D but a seperate adaption device (not included) will be needed first.
smaller screens aren't exactly bad but the larger screens are certainly more impressive. remember, the 3D effects won't extend of the side of the screen so the larger the screen the more 3D awsomeness.
i can't comment on the particulars of the glasses. as i understand it each pair of glasses is uniquely tuned for a specific tv (i.e. glasses for a sony tv won't work with glasses for a samsung tv and vice versa) so if there is any major differences make sure you understand them before you purchase a 3D tv.
oh and gratz on your future purchase. i'm kind of in the market for one too but i'm waiting for lbp2, killzone3, ect to release first.
