Hi L.-
To make it easier on you, the first thing I would suggest is to go ahead and put the kids favorite shows on the schedule and build the rest of the schedule around that. I know it's sounds terrible to let TV be the center of the schedule, but given your circumstances I think the transition will be easier on the kids if their favorite shows are still a part of their day and it's just the "extra TV" watching that you're eliminating. Once you have that set, fill in naptime, mealtime, and any scheduled activities. Now that you have a basic map of your day start filling in the holes.
Do you have a backyard area or park close by that they can play at while you rest nearby? If so, include outside playtime in the morning before it gets too hot. I would suggest a quiet activity prior to naptime so that they wind down and are ready to nap. Story time is always good for that.
For arts and crafts I would suggest stocking up on the basics (glue sticks, crayons, colored papers, foam stickers, fingerpaints, etc.) and going to Michaels or Hobby Lobby for some unique and usually inexpensive craft ideas for the boys. Buy a plastic party tablecloth to put out on your kitchen table at craft time -- it will save you a lot of headaches.
How about cooking together? It doesn't have to be anything elaborate, you can even just include them in the meal preparation each day.
Good Luck,
K.
