First Year Fantasy Baseball Commissioner Help

Hi, my buddies and I are playing fantasy baseball for the first time this year and I'm setting up the league. It's on yahoo, 12 team H2H points. I've adjusted stats and rosters based on what I've seen on the subreddit but would like some feedback before the league drafts tomorrow.

As of now the rosters are C, 1B, 2B, SS, 3B, 3 OF, 1 UTIL, 4 SP, 2 RP, 5 BN

Scoring (Offense): R = 1, 1B = 1, 2B = 2, 3B = 3, HR = 4, RBI = 1, SB = 2, CS = -1, BB = 1, HBP = 1, K = -.5

Scoring (Pitching): IP = 3, W = 4, L = -4, QS = 4, SV = 4, BSV = -2, HLD = 2, H = -1, ER = -2, BB = -1, HBP = -1, K = 1, Shutout = 15, No hitter = 25, Perfect game = 40

Any advice is appreciated, completely new to this
