2 years a go i set about creating one of the most accurate daft punk helmet replicas in the world -

since then i have spent my time both selling the helmets and working on my own led replica. here's how it will look -

So basically i have designed all my parts to hold all my leds bought all the pcbs i need etc. parts have been laser cut from acrylic and cnc'd from carbon fiber. its getting close to the end but im stuck on one part of the build. Im experienced with soldering and stuff but this is over my head.
I need this board to power the following -
channel 1 - 2 sets of 8 yellow rectangular 2.1V 30ma leds ( one set of 8 for the left and one right side of the helmet)
channel 2 - 2 sets of 8 red rectangular 2v 25ma leds ( one set of 8 for the left and one right side of the helmet)
channel 3 - 2 sets of 8 green rectangular 2.2V 25ma leds ( one set of 8 for the left and one right side of the helmet)
channel 4 - 2 sets of 2 yellow rectangular 2.1V 30ma leds + 1 5mm 3.2v – 3.8v blue led ( one set for the left and one right side of the helmet)
channel 4 - 2 sets of 2 yellow rectangular 2.1V 30ma leds + 1 5mm 3.2v – 3.8v blue led ( one set for the left and one right side of the helmet)
channel 6 - 2 sets of 2 red rectangular 2v 25ma leds + 1 5mm 1.8v – 2.2v green led ( one set for the left and one right side of the helmet)
channel 7 - 2 sets of 2 green rectangular 2.2V 25ma leds + 1 5mm 1.8v – 2.2v green led ( one set for the left and one right side of the helmet)
When i bought it i was given instructions and a diagram =

1. The resistor R1 should be a 1,000 ohm resistor (1k) to the base (B) of the transistor.
2. The emitter (E) connects to ground.
3. The collector (C) connects to the bank of your LEDs.
4. R1 then connects to Output 1 on the chaser board.
5. Your LEDs connect between (C) and +V. You may need a resistor R2 as well. If so it depends on how many LEDs and their voltage level.
6. +V depends on the voltage level of the LEDs.
7. Then repeat for Outputs 2 to 8.
So from each channel of the chaser i need to power 2 sets of 8 leds. (one set one side of my project and the other set on the other)
It shows in the diagram the leds are connected between "C" and a +V. firstly is this +V from another source? say the 9v battery powering the chaser itself? or would this even be enough power?
So say i had 2 sets of 8 leds (2v 25ma each led) in parallel connected between "C" and a +V. what should the power of the +V be? also what resistors would i need? and where would these be placed? before the 2 sets in parallel, before each set of 8 in series, before each individual led?
Also i take it if the +V comes from a separate power source so thats where i connect E?
I have mentioned having each set of 8 leds in series, but this may also not be the best way, so if they would be better in a different arrangement thats fine.
