How to better level up with a Spear/Katana build and which equipment special skills to search for?

I decided to proceed with a defensive (Tank) build, with main weapon Spear and 2nd weapon Katana, with an alternative 2nd weapon the axe.

My initial thought was to proceed on leveling all stats until 10 and then every 2 points I add to Strength to add 1 to Stamina and add 1 to Spirit. Is this the correct way to go for such a build?

Also which special skills or sets should I chase/prefer for this kind of build?

Note: This is my first souls-like game, so everything is a challenge.
