ok in that case you may want to brush up on your mtt skills and start reading that forum, because thats what these are, this forum is more for stt, not that your not posting in the right area, but you'll find a lot of usefull info over there, also that changes things a bit...what you should be doing is:
10/20:
limp pp's, sc's, Axsuited (also call w/ these if you have pot odds in the area of 3:1 or better as long as it's less than 1/10 your stack)
raise: AJ+, 99+ and hefty raises (80-120)
fold everything else
15/30
same as 10/20 only when raising make it 120-150
25/50
limp: pp's in mp-lp or in the sb, sc's in the sb or co-otb, Axsuited mp-lp/sb
raise: A9s, AT+, 88+, 150 should be the stnd opening raise 200 if you have 1-2 limpers
raise the button when it folds to you and you have any of the hands mentioned above for limping or raising except Ax or Kx; 3xbb works just fine
50/100
this level is stack dependant but you need to keep a weather eye on the tournament lobby, in the 18 manners you'll most likely be at the ft at this point so disregard, but for others you need to see if your stack is on par w/ the avg stack if not you need to be rediculously aggro to get a huge stack, as these donkaments' prize pool is weighted so much to the top 3 players...remember your playing for 1st place so act accordingly.
