Highlighting Cells

If I have values highlighted in column C (using conditional formatting), can I set a rule where the highlight array gets copied the the column directly next to it (column B)?

I have another question which is similar enough so I can ask in the same thread: Is there a rule or criteria you can set (and it doesn't have to necessarily involve conditional formatting) where you can highlight values in column A based on values that are highlighted in column B? (No formulas or rules set) ie. if I have 1,2,3,4,5,6,7,8,9,10 in column A, and 8,9,10 are highlighted in an array, highlight all the 8,9,10's the same way in column B...

Attachment Directions:

1. Copy highlight array directly from column C to column B (have them automatically update), once complete,

2. Highlight column A values which match those highlighted in column B...
