Quick questions regarding Herbie style drain

[rocketlily]

I hope to finish the plumbing today, and I need to know:

1) How far do you extend the 1 1/2" pipe under the water level in the sump for the main drain?
2) Do you solid pipe or perferated (with holes) under the sump water level?
3) Do you use a standpipe on the main drain bulkhead or just drain through the bulkhead.

Thank you
