Setting Publishing Point Limits

[Joshi@discussions.microsoft.com Milind Joshi]

I have a VPS server that I am using for my live content delivery. I have
setup the publishing point to be 'pushed' type. I would like to know what
should be the various limits if,

1) Only one publishing point (Unicast) will be active.
2) Most of the times my number of clients would not exceed more than 50.
3) I am encoding using 282 Kbps + 148 Kbps, for live broadcast.

I'm especially interested in knowing the ideal settings for:
Limit aggregate player bandwidth, Limit bandwidth per stream per player,
Limit incoming bandwidth etc. I went through a document about optimization
that mentions that some of these should not be left at 'Unlimited'.

Thanks.
