I think your main issue is compaction Nick. To test drainage dig a hole about a foot deep and fill with water. If it drains well you're not on clay if it doesn't you may well be on clay. Clay is easy to spot if it's wetted you can roll it into a ball or squeeze in your hand and it won't break up. If it's clay you can lay pea shingle and manure then rotavate. If it's not clay you don't need the grit or pea shingle, just manure.
