Only a couple of days? The high level skills in eve can take up to a month to develop.

When I was multiboxing eve lots of time ago (a couple of years) I had one specialized tackler one specialized drainer and one specialized damager. That way you can have the best of all these skills in a single ship and play your 3 ships as one.

Of course, I suggest you to get a rifter frigate and gear it with cruiser afterburner with maxed capitanship or whatever it was called the skill that makes your ship go faster. That's just for the lols if you want to be really fast. I used one such thing instead of a shuttle because it was like 5 times faster and was cutting my travel time alot when going to sell expensive blueprints. The extra cargo space also came very handy.
