Asked: How’s my White 2 team looking?

I'm three gyms in, and this is my third playthrough of a Generation V game. I'm at the third gym, so my team is relatively low leveled. I'm not playing competitively, so I don't intend to replace my team solely because of a bad nature. My team is as follows:

Whirlipede – Poison Point – Docile
Venoshock – Rollout – Poison Tail (replace with Toxic?) – Bug Bite

Crobat (shiny!) – Inner Focus – Brave
Wing Attack (replace with Toxic?) – Confuse Ray – Fly – Bite

Pignite – Blaze – Adamant
Arm Thrust (replace?) – Flame Charge – Ember (replace!) – Rollout

Herdier – Sand Rush – Lonely
Work Up (replace with Sandstorm?) – Strength – Dig – Bite

Flaffy – Static – Naive
Take Down (replace?) – Charge – Thunder Wave – ThunderShock (replace with Thunderbolt)

Psyduck – Cloud Nine – Quiet
Disable – Confusion – Fury Swipes (replace?) – Water Pulse

My only concern is an overall weakness to Psychic types. I have a few dark and bug attacks to counter it, but I'm not sure it's enough. I also have no way of countering a powerful ground type, since I don't readily understand them.

Am I fine, or do I need to beef up my team?
