So the Warlord Wars of Religion figures are very 1560's - fine for Roanoake probably too old fashioned for Jamestown.
By the very early 1600's the ruff was on its way out, in favour of the 'falling bands' style lace collar. Ruffs hung on until the mid 1600s, but tended to be fairly out of fashion. Body wear was the shirt and doublet; slashed sleeves were getting less common and were very much at the rich end of fashion. The 'soldier coat' of the English Civil war was around as a working mans coat.
Legwear was mostly 'Venetian' britches without much in the way of puff and slash.
As a general rule, think 3 musketeers and English civil war rather than Landsknecht.
Swords were still mostly hung from belts, although baldrics were starting to come into fashion.
The morion, cabasset and burgonet helmets were in fashion, the classic lobster pot is still a few years away.
Hats tend to be broad brimmed, "cavalier style". The Tudor "pork pie" caps will probably be ok for Englishmen for a few more years.
Bandoliers/"twelve apostles" for musketeers. Fire arms are muskets (with rests) and smaller, lighter, calivers. Longbows for the English are very much in decline.

Assorted New England Militia, mostly 1620';s from memory

English Militia, Jamestown, 1610s

The two on the right are supposed to be English settlers in north America, 1610's-1620s
The TYW swordsmen are spot on, especially for officers. The Warlord TYW/ECW plastics work fairly well.
