Answer 1

Do you really need to implement a custom ModelBinder here? The default binder may do what you need (as it can populate collections and complex objects):

Lets say your controller action looks like this:

public ActionResult SomeAction(Fund fund)
{
  //do some stuff
  return View();
}

And you html contains this:

The default model binder should initialise your fund object with 2 items in the FundAllocations List (I don't know what your FundAllocation class looks like, so I made up a single property "SomeProperty"). Just be sure to include those "fund.FundAllocations.Index" elements (which the default binder looks at for it's own use), that got me when I tried to get this working).
