Hi Bob,
You can "suggest" a crawl rate to Google by logging into your webmasters tools on Google and adjusting it there.
As for indexing pages.. I looked at your robots and site. It really looks like you need to employ some No Follow on some of your internal linking, specifically on the product page filters, that alone could reduce the total number of URLS that the crawlers even attempts to look at.
Additionally your sitemap http://premium-hookahs.nl/sitemap.xml shows a change frequency of daily, and probably should be broken out between Pages / Images so you end up using two sitemaps one for images and one for pages. You may also want to review what is in there. Using ScreamingFrog (free) the sitemap I made (link) only shows about 100 urls.
Hope it helps,
Don
