Answer 1

This link provides a lot of good D/P jargon:

UU, I think, stands for Underused and OU mean Overused.

EV's are Effort Values.  They're kind of hard to explain but they can increase your poke's stats by a LOT.  Each pokemon you beat gives a certain number of EV points (check a reference list) in one or more stats.  For every 4 effort points in one stat, the pokemon gains 1 more actual point in that stat when it levels up.  A pokemon has a maximum of 516 max effort points availible to 'spend'.

Example:  A Garchomp has high base speed and attack.  Without EV training, it will waste effort points on stats that it normally never uses, like Special Attack.  

A Garchomp that is, say, level 50 and beats 20 Bibarel (which give 2 EV's in attack each) will get a bonus (20*2)/4 points boost in attack when it levels up, a 10 point attack boost!  And even more if it is equipped with a certain 'power' item, which give extra EV's.

So EV training is really hard and takes a long time but can make your pokemon more powerful in its dominant stats.

IV's are individual values, each pokemon has different ones, they provide a slight boost or drop in some stats.  These are impossible to change unless you find a new pokemon.  Don't worry about these too much.

Answer 2

I believe they are "Over Used" and "Under Used".
