Xoutpost.com - Newbie here looking for advice please

Hi All ,Newbie here and looking for some advice please ,had a E53 before but went to Range rover and now back to a e70 :),I have a few questions so would be very grateful for any hints /tips ,Unfortunately I'm currently offshore overseas ( but live in UK) with very slow internet access so restricts my ability to troll through the forum ,

1) I have a 3.0D SE 2007 and would like to update this to the 2011 facelift model ,I know I need new wings /bumper/rear lights/rear bumper/arch extensions etc but can i retain the 2007 headlights/ bonnet ? what else is needed?

2)Does anyone have a list of the types of all the interior/exterior lights /door handle lights etc for converting to LED lighting ? My car has standard halogen headlights and as far as I'm aware these have different bulb fitments than the H8 type?

3) I had 285/35/22 extra load wheels on my range rover sport are these suited to the X5 ( I've read yes but thought id ask opinions on here ) I assume id def need the arch extensions and do you recommend running these wheels with or with out spacers to get the staggered look or is it really a waste of time with the width of these wheels anyway.

4) lastly with my previous bmw's ( e60 and e53 ) I used inpas and other stuff ( cant remember as it was about 5 yrs ago) for coding and fault finding what do you people recommend now ?

Sorry for the long winded post peeps but the internet is slower than a slow thing down here so thought id get it all in in on one post ,thanks in advance .
