University choices..?

So um.. I haven't really got a clue about how I'm supposed to be going about this, just that in september I started UCAS and i'm not really sure when that's supposed to be completed..
I'm doing BTEC Art and Graphic Design... and so far my choices are

UCA - University for Creative Arts Farnham
LCC - London Communications
UAL Chelsea College of Arts
Kingston University [ though that feels like a maybe... ]
EDIT : I think i made my final choice for Hertferdshire..

I needs two ish more to choose from, I really am trying to stay within London because of expenses and also my health, I've had an issue where I blackout a lot.. and moving too far just makes me anxious, but I'm finally getting close to a diagnosis [after two years i have a huge medical history .__. ].

So... my questions are..
Anyone know any good unis ?
Should I put them down on UCAS after I visit them... ?
and i totally forgot what else I was gonna ask... It'll probably come back to me

EDIT** I'm totally stuck between picking Graphics and Architecture and what I need for my portfolios now..
