For seed starting indoors: Would you rather use a Burpee's Ultimate Seed Starting System or a regular watering tray, clear dome, and cell packs. or Park Seed Bio Dome
Whichever you like.* I use plastic wrap over my cells and a cookie cooling rack placed in a roasting pan.*
Also do you think the Burpee's Automator would help for a beginner gardener like me?
I've never used anything like that, but it seems to me that it might be helpful in a cold climate, not in a warm climate like yours.
Would you rather use a PVC Tomato Cage or buy a Burpee's Tomato Cage
That depends on your budget and your DIY skills.** If you don't think you can safely cut the pvc pipes and assemble them, then maybe the tomato cages will be best.* I do like the square ones better then the round ones.

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
