You have the T5 high lites in that tank which will be fine for softies and some corals like Hammers, frogspwan etc - you can boost the lights by getting reflectors

I would personally keep the lights you have got and upgrade later if you want to (could then look out for a bargain halide or Aqua Rays)
I have the same tank as you wih fresh water fish and have been thinking about turning it into Marine as well - unfortunatly though I have the old T8s in there

so will stick with my nano for now
Search for local reefers breaking down a tank for your lr - if you do transport the lr, do so in water - I transported mine for 45 minutes in tubs of water and had very little die off
As for the skimmer - I was looking at getting the TMC v2 400 - aquatics warehouse seem to be the best price I could find although you might get yourself a bargain on fleabay
oh and by the way

to the salty side, it is a fun place to be = patience is a virture over here
