what grain can be substituted as an extract

[drykill8]

Hi,
My name is Jesse, been homebrewing for about a year. started with the Mr.beer kit....made 3 beers that aggravated me with the taste. Moved up to mini mash 5 gallon and made a few not to share with friends, one awesome clone of Punk IPA by Brewdogs a few other decent hefeweizens. I now have an imperial ipa bottle conditioning, my own wild idea to make an ipa hefeweizen summer ale hybrid bottle conditioning, a chocolate porter in secondary and a pumpkin milk stout in primary. I've watched all the brewing TV episodes and i'm almost finished with John palmer's how to brew. My question is how do I take an all grain recipe and make it a mini mash. These are the grains and amounts. 5.3 lbs pilsner malt, 5.3 lbs light munich malt, 12 Oz 20L crystal malt.
Thank you everyone that can assist

There are extract versions of pilsner & munich malts. Here's a handy conversion chart that may help; http://www.jaysbrewing.com/2011/11/17/lazy-chart-for-converting-dme-lme-grain/
At some point, you may want to get software like Beersmith that can do the conversions for you, among many other useful things; http://beersmith.com/
