If you find yourself needing to use patterns like this often, then you may be interested in trying out the async.js library. Using async.js you could write something like this:

function getAll(callback) {
    redis.lrange('mykey', 0, -1, function(err, reply) {
        async.concat(reply, redis.hgetall, callback);
    });
};

Which basically means "call hgetall on each item in 'reply' then concat all the results and pass to the callback".
