Thanks for all your responses. I am having a great time with this game. Basically what I gather from all the responses is:
A) Pay attenion to the learning skills first since this will lessen the time to train the other skills?

Since I am mostly armor tanking, I should not worry about the shield related skills?
C) Don't worry about taking a skill past 4 until much later?
BTW, the ships I am using right now is, a punisher for missions:
-three multifreq lasers and a syphon laser in high
-overdrive and barton's cap recharger in med
-dam control, remote armor repairer some armor regen stuff in the low
-I have been thinking of switching to a salvager in place of the syphon laser for some missions.
For mining I have been using a tormentor with two mining lasers in the high and exp cargo holds in the low. I have been using a Sigil to pick up jet cans.
I feel I am heading the right direction, what do you experts think?
BTW Inuke's guide was a big help.
