Having a directory structure is good.

Having a sitemap that lists a lot of stuff is good.

Having multiple sitemaps is also good.

If Google is going to only devote so much crawl strength to you, then you just have to prioritize where you want it to go. Do you need a level two page crawled daily, or do you need 100 level four pages crawled once a month? Point your links and distribute your pagerank accordingly.
