Do that only if you're planning on becoming a STR build. Had that on my first character, and the mobs became easy mode, until I had to change my weapon after reaching Anor Londo (made a lightning zwei; lightning weapons will be nerfed this coming patch though, so don't count on it just yet). Or you could get the Claymore sword. Has a better moveset (R2 specifically) than the BK sword and less stat requirements (16 str).
Oh, and you don't get the Black Knight armor til the last dungeon of the game. No stat requirements for armor btw, but they're somewhere in between the Black Iron and Elite Knight Set. Might have to increase your endurance if you plan on removing Havel's Ring (if you've killed him already).
There's a similar-looking armor called the Silver Knights set, which is much inferior than its black counterpart, but you get it mid-game in Anor Londo.
