I have a Weber charcoal grill. I heard you should bake your chicken before you grill it…is this correct? How should I prepare and cook the chicken safely and make it delicious?

So we decided to get a Weber grill but have questions about some of the differences between different models of Weber grills. I checked Weber’s website and they have no information about the following::
1. One type of grill has a “crossover” ignition, while the other type has an “electronic crossover” ignition. What’s a “crossover ignition” and what’s the difference between the two different types of ignitions?
2. One grill has porcelain enameled cooking grates, while the other has porcelain coated cast iron. When the grill has porcelain enameled cooking grates, what material does the porcelain enamel cover?
3. Is a sideburner worth the extra cost?
Thanks for the help.

I have never grilled before, and now I’m very tempted to try my hand at it. I don’t have much space (1 bdrm apt) and will have to grill outside our apartment building, so I want to buy a Weber Smokey Joe portable grill. My question isn’t about the grill, but how to safely light, maintain, and dispose of charcoal as I use my grill. Anyone have any tips, tricks, or simple directions?
Experienced Smokey Joe users are especially encouraged to answer!!!
Thanks!!! :)
