Advice please re storing 'rusty leaved' onions and garlic

Hiya!!
Our autumn planted onions (Radar) are all flopping over and one of our varieties of garlic (Provence Wight) are very yellowed so I think theyre ready to come up. The garlic has got rust really badly and the onions have a little bit and I was wondering how I will store them, if they will store at all. Last year our onions were rust free and we dried them for a couple of weeks and then I platted them in strings to hang in the shed, which worked really well. Can I do that this year or do I need to strip all the rusty leaves off? how else can I store them?

Thanks
