Well, the SP-Levels comparison is an easy one to fall into, but it is largely entirely false.
Skills mostly just open up options. They give you more things to fly, maybe a bit more flexibility in what you put on them. Even the skills that increase some particular stat across all ship largely max out at 25%.
So, you can't fit every module right away, and you can't fly every ship, and you have a fraction (25% or less) less in a few stats than my character (after a length of time playing on my part that hardly bears thinking about.) A few fairly new players in inexpensive ships can easily take on a solo vet in anything sub-capital, in most cases, and win.
What really tells - and takes time to acquire - is player knowledge and skill. What do do in a situation. How to fit a ship effectively. Where you can go and can't go. What effective ways of making ISK are. (ISK, up to a certain point, is much closer to representing 'levels' than SP is. ISK is what decides what you can afford to fly, and what you can afford to fit it with.)
When you go to low sec (Low sec starts at .4, and goes to .1 - in .5 and up, people can't attack you with getting CONCORDed unless you do something to allow them to, like taking something out of a can that belongs to them) it isn't how old your character is that determines if you are going to survive. It is if you, the player, know how to survive there.
And not to worry: There are guides, and when you are new, the price of your mistakes is usually fairly low, though it may not always seem that way at the time. The player skill will come with playing.
As for SP, and training, you should set a goal. Decide something you want to do. A good initial goal might be getting into a Battlecruiser, for example. Find out what you need to train, and train for it.
Anyway, if you have questions or anything and I'm around IG, feel free to ask, or PM me here.
And I would try to find a *good* corporation fairly soon. A good corporation can make the game for you, and a bad one can really drag it down. 30 days in is plenty to start looking.
