You should put pre-emergent herbicide and fertilizer on your lawn in the spring. Pre-emergent herbicide keeps weeds from taking root. Fertilizer helps your grass to grow lush and dense and blocks future weeds from growing. You can also add amendments, such as sulfur and lime, to enhance your soil quality. 

A lawn that suddenly and quickly turns yellow is typically the result of a dramatic change in the grass's environment. Heavy rainfall can dilute soil nutrients, rapidly yellowing the grass, and dull lawn mower blades can dry out and damage the grass in a short time. Over-fertilizing can yellow a lawn within a matter of days. 

Whether or not grass will fill in bare spots itself depends on the type of grass you have. For example, grass with rhizomes (e.g., Bermuda grass) and stolons (e.g., Saint Augustine grass) will naturally fill in bald spots as it spreads laterally. However, clump-forming grasses will not spread. 

Aeration can level your lawn if the issue is minor soil compaction, so it can help smooth things out if your yard is bumpy from foot traffic or vehicle traffic. However, it won’t slope your yard. If you have small areas where water seems to pool after precipitation, aeration could help, but larger issues with improperly sloped lawns and problems leading to foundation leaks or structural damage will require more comprehensive solutions.
