My capsi*** and aubergine plants

Well, they grew to be sturdy, multiple leaved plants, over 12" tall and
with 
a big spread. They're now in maximum size pots on the greenhouse staging
and 
I've staked the tallest - need some more canes <note to self: ask Spouse
to 
make something>.

So far so good, now I need more advice please.

There are some white flowers on some of the peppers and buds on the 
aubergines. Do I need to do any hand pollinating?
