grep and map can probably help. First, to get a subset of hash keys:
my @a_keys = grep {/a/} (keys %names);

Then to get their values:
my @a_values = map {$names{$_}} grep {/a/} (keys %names);

You could also get the job done using hash slices, like so:
my @a_values = @names{grep {/a/} keys %names};

That's more like the syntax you proposed, though I find it a bit disconcerting (maybe because I don't find the @names{...} hash-slice notation particularly natural in the first place).

Update: only answered half the question in my original reply. Fixed here.
