No, let's see. You start with one dot in all your attributes (it makes no sense to have 0 INT unless you are JK5). Then you have to prioritize the attribute groups (social, mental, and physical) in the order you think is best/makes more sense for your character.
Let's say you prioritize like this: first physical, then social, then mental. Then you would have 7 dots to spend in the physical attributes (which makes a total of 10 dots since you have 1 free dot in each attribute which you can't assign anywhere else), 5 in social, and 3 in mental. You cannot mix and match, you must spend those points in the attributes according to the priorities you have chosen.
The process is similar with the abilities and advantages, only those don't have free dots, if you don't spend dots there, they stay at level 0. For your abilites you have 13 dots to spend in the first category, 9 in the second, and 5 in the third, again all according to the priorities you choose.
For the advantages, you have 3 dots to spend in Disciplines, 5 in backgrounds, and 7 for your virtues. Those are fixed and you cannot prioritize them. As you are playing as a Ventrue, I would suggest that you spend at least 3 of your virtue dots to decrease your generation, as Dominate is useless if you use it against a vampire of a lower generation than your own.
Now for Humanity, its value is equal to Conscience + Self Control, and Willpower is equal to Courage.
Note that we were talking about dots. Now, you can spend the 50 freebie points in whatever you want, according to the chart posted before. Thus, if you wanted to raise an attribute by one dot, it would cost you 7 freebie points, and so on.
Any more questions, post them.
