Serration is good. Maxing it is kind of overkill. You can get through the game with just 75% basic damage.

Armor Pierce is a must when most armored enemies reduce your damage by mroe than half. Get a mod to at least 50%. It works against all factions, though Corpus and Grineer take the most damage from it, and it stacks with Serration. Only downside is that it does not work against shields.

Freeze damage is also great. It is more effective against shields, which makes up for the lack of armor pierce damage to shields. It also has a slow effect, which is very helpful vs ancients and infested.

Everything else is basically optional. I personally find electric and fire damage take too many mod points and too situational to be worth it. You can also use utility mods. I find I need more bullets at lower levels, so i take max ammo sometimes.
