MacBook :: Opinions On Apple UK Repair Quality?

After many MANY issues with My beloved 7 - 8 month Macbook black 2.4ghz, 2gm RAM, 250GB HDD I have decided its time to take it in for a repair

The issues are as follows

1) Cracked Keyboard, right palm rest area where the magnet touches the palmrest area, this has led to:

2) Due to there being the crack, the magnet actually fits neatly into the crack when the lid is closes, this has scratched the right maget and the LCD bezel

3) The LCD has a purple horizontol line going through it, cant see it all when on net where there is a white backround like in Macrumors forum however when watching a film where it is black the purple line is highly visible making film viewing difficult

4) On the left bottom side where the two screws are located there is a "Bulge" as in the plastic housing is loose, this affects the entire left side where the ports are more or less but in between the two screws and to some extent up to the headphone jack you can practically push it in around 2mm, when doing this it makes a really annoying squeaky sound. Due to the bulging, there is a small crack forming under one of the two screws

5) This Baby has major overheating issues, right now Ive just got back from College and had this thing on for about an hour, just with simple Safari Browsing the CPU has temp of 55 degrees celsius and airport card is a whopping 64 degrees celsius, this will easily rise to a temp of around 60 for the CPU and around 68 for the airport card in the next hour again with simple internet browsing such as looking at forums and news

6) The Hinge is very loose, If I pick up my macbook and sort of shake it like thurst it forward the Hinge will come move and I could technically close it like that but cant as it hits hard.

Ive found it really disgusting that paying a small fortune for this laptop (Im a student and this Mac really required some hard work to pay for it) It has this many problems, I was going to give it in earlier but as this is my primary computer I didnt have the time to give it in but now as Exams are over I think it needs a major repair, even an upgrade which Im sure I deserve

So as a newbie to this Apple repair process what happens, Ive booked a genius bar appointment for tomorrow (can change if needed) Do I simply walk up to the genius and tell him my problems, and what to Apple do, do they repair it in store or send it out as Ive read some pretty bad stories about how Apple take care of your product, ive got a small few scratches on the bottom base which are unavoidable and one small hairline one the back but other than that its in tip top condition
