what should i train him in most? second most?

Strenth and speed thin blocking.

so strength and speed, and a little bit of blocking?

Strength
Strength
Agility
Agility
Strength
Agility

Is how to start any FB. Then you can decide if you want to be blocking/balanced/rushing/receiving

EDIT: I see this might be your first player. Familiarize yourself with http://www.glbwiki.com/index.php?title=Ability_Softcaps and http://www.glbwiki.com/index.php?title=Build_Strategies_Comparison#Slow_Build_-_Soft_cap_focused

I like to build a blocking FB like an O lineman at first. Then switch up and focus on speed.

So basically:

Strenght/Blocking till strength is 24+ and you have enopugh SP to cap it at 48
Blocking/agility while taking strength to 68
agility/stamina while taking blocking to 60
speed/stamina while taking agility to 68
vision/confidence while taking speed to 68
