FWIW, your latest breakdown also allows you to run a decent 9-player deep-stack tournament with ease:
T400 stacks
20 x T1
16 x T5
8 x T25
1 x T100

45 chips = T400
Blind structure (200BB)

L1 1 2
L2 1 3
L3 2 4

L5 4 8
remove T1 chips (use T5 chips)
L6 5 10
L7 5 15
L8 10 20
L9 15 30
L10 20 40
remove T5 chips (use T100 chips)
L11 25 50

L13 50 100
L14 75 150
L15 100 200 ***
L16 150 300
Tournament is unlikely to end any later than L15 (3:45 with 15-minute levels, or 5:00 with 20-minute levels).
However, for your cash games, I'd want a lot more $1's and $5's on the table.... at least another rack of each. In general, more workhorse chips promotes loose play, while fewer workhorse chips (and more higher denominations) in play tends to tighten up a group's play. Players with lots and lots of chips tend to be more willing to bet/call/raise.
