For an assistant store manager role at Sherwin-Williams Company, what skills are going to help me succeed?

Ability to multitask will help you a lot in this role. Customer service is also paramount within SW. This role will also be a good fit for you if you like having a variety of responsibilities within the business. For example you are likely to lead the accounts receivable efforts for your store, the lead generation, share responsibility with the manager for ordering and managing inventory, driving sales & gallons growth, etc... The more willing you are to make yourself a sponge and learn from those around you, the more successful you will be.
