Reply to working abroad this summer.. a couple of questions??

hey guys, i have the opportunity of a residency in portugal this summer and have a couple of questions about my gear, i know some of these may have been answered already but here goes,

my mbp power supply.. i have a uk supply, will i just need to change the extension part to an eu plug or do i need a new supply?

hand luggage.. will i be fine carrying my laptop / soundcard etc with me, and just check in everything else

finally tools.. i always carry a few tools, eg screwdrivers cutters extra cables etc with me, will they be ok in my checked in case or am i better to have all of that posted out to me??

portugal is somewhere ive never visited, if anyone has is there anywhere you guys would recommend for days out etc..

cheers as always
