Yes,

You should only have 1 Gun spec until its gets to late 80's. After that raise the second. Also your starting SPECIAL should has a major impact on what you raise first. For instance my spec at level 1 is.

Str 1
Per 10
End 7
Car 1
Int 10
Aig 1
Luc 10

The reason for high luck is you get 1 point in all stats for every 2 luck points so 10 points in luck gives use 10% crit and 5 points in every stat. High Perception is mostly because I use energy weapons. High intelligence gives me maximum points per level (20) from the very start and 7 in End gives me 300+ health.

For my 3 tag skills I pick Science, Repair and Lockpick. I focus on getting these 3 skills to there shelves (25,50,75,100) with repair taking priority and lockpick second.

With my build each of my tag skills starts in its late 40's this means I can but only a few points into them and dump some points into energy weapons. At level 3 you get the perk that gives 3 extra points per level. I dump these extra points into medicene as i love stimpaks!
