Advice On Skin Care Regime?

Ok, Well I'm An 18 Year Old Guy And I Just Need Some Advice On A Couple Of Skincare Ideas... To Begin, Basically I Have Pretty Sensitive And Dry Skin, And It Is Also Slightly Acne Prone. I Finished Taking An Isotane (anti-acne) Course About Two Months Ago, Which Got Rid Of Most Of My Acne, Although I Have Some Marks On My Checks. In The Morning And And Night I Use "neutrogena Oil Free Acne Wash, Cream Cleanser" W Salicylic Acid. Then I Moisturize With L'OREAL Men Expert Hydra-sensitive. Occasionally, I Use "Garnier Prue Active Blackhead Clearing Scrub" W Salicylic Acid As A Exfoliater.  Last Of All I Have Just Begun Using Benzac AC 2.5% To Combat Occasional Spots. Now For The Questions... Is It Normal For My Skin To Feel Tight/dry After Cleansing And Before Moisturizing? Also Recently I Have Been Getting Whiteheads Around My Mouth And Chin, What Could Be Causing This And What Would Be The Best Way To Stop It? (I Have Been Told That Using Lip Balm A Lot Can Cause This, Which I Have Stopped As Of Yesterday) What Could I Use To Help Remove Acne Scars On My Checks? Finally, Is The Products I Use Good For My Skin Type? (sensitive/dry)  What Other Products Could You Recommend That Would Be Beneficial While Also Keep Away Basic Acne?  Does My Regime Cover All The Basics Of Skincare? Thanks In Advance
