Hello Barry & welcome to the site. Slow & steady is the order of the day, particularly in your case but is usually recommended to newbies. Try to cover some of your ground to suppress the weeds, excluding light encourages them to die, cardboard, black polythene or better still weed membrane ( you can use it again & again if you get the woven type). If you have raised beds in the future you could use it for the paths &cover with wood chips to make sevicable paths.
