Early 4th Job builds widely vary from person to person. Depending on your preferential way of leveling, you may choose to get different skills at different times. Personally, I try to avoid having many different attacks and aim for simplicity. My builds derive from that principle. They aim to max the skills that deal the most damage at maximum level first, so that later levels are easier to obtain (somewhat).
However, others may feel differently and some like having a multitude of skills to train with. If you are one of these people, feel free to throw points wherever you'd like; by 200 it won't really matter, as long as you have your important skills maxed. An example is of people putting early (120-121) points into Wrath of the Octopi and Elemental Boost. The Octopi's attack speed greatly increases (from what I have read), and level 1 EB increases your damage on FT/IS by a significant amount (22%). Depending on where/how you train, they might be beneficial to raise early on.
Regarding Mastery Books:
Please note that the availability of Mastery Books depend on the server.
If you are in a busier server such as Scania or Bera, it will be very easy for you to locate your Mastery Books. However, in servers like Kradia or Dementhos, where populations are very low, it may be exceedingly difficult to find skill books.
In this case, I recommend you save up several points for when you do obtain the books, and begin putting SP into other skills.
None of your main training skills require you to "learn" the skill via Mastery Book (Ie, TripleThrow10 for Night Lords), and so you can go ahead and spend points into other skills while looking for Mastery Books.
I personally have (had) difficulty finding Torpedo20/30 in particular, and so I will be saving 5 points (for level 15 Torpedo which hits 5 monsters) and putting any more points into Cannon. If I cannot find the Books for Cannon, I will most likely move onto Bullseye, then Pirate's Revenge.
Finally, please remember these are general guidelines, not hard-and-fast builds. I would very honestly recommend you judge how/where you're going to train and allot skills according.
