Worksheet consolidation, VBA. Stop copying column headers

In the code below:

For Each ws In Worksheets
        LR = ws.Range("A" & Rows.Count).End(xlUp).Row
            ws.Range("A2:F" & LR).Copy
            Me.Range("A" & Rows.Count).End(xlUp).Offset(1).PasteSpecial xlPasteValuesAndNumberFormats
Next ws

LR = Range("A" & Rows.Count).End(xlUp).Row
With Range("A2:F" & LR)

What does the "&" mean in ws.range("A2:F" & LR)? Is it like the word AND?

Same thing with [code] With Range("A2:F" & LR)?

Also what does the following code do?

.FormatConditions.Add Type:=xlExpression, Formula1:="=MOD(ROW(),2)=0"

thanks
