March 5-15 is when you need to get down a pre emergent weed killer. This is the weed killer for grassy weeds, like crabgrass and dallis grass. Wait until later and you might was well save money and skip it - the grassy weeds will already be germinated.
Don't use a weed and feed. The fertilizer will just wash away since the grass won't use it yet. Never do fertilizer until your yard is actively growing. For my St. A, that'll be around April 15 - May 1.
If you have leafy weeds, like henbit and dandelions, use a 2-4,D locally on them. They're easy to see right now since your yard is still dormant.
