Reddit mentions of Cole Haan Men's Grant BIT, Tan Grain, 12 M US

Can't help you with the pants thing, but the shoes I can.
Business shoes:

• First option would be the classic business penny loafer: http://www.brassboot.com/shop/style/93391-222.html These will go with just about any business/casual look you can think of, from formal to denim. Certainly one of the most versatile types of shoes in and out of the business world, anything this style will suit your needs. Brassboot is one of my personal favorites, but any penny loafers will be a definite good bet.
  
  
• If you prefer something that many think is more casual, you can try the driving shoe (also known as frat cleats due to their prevalence in southern frat style): http://www.amazon.com/Polo-Ralph-Lauren-Up-Leather/dp/B003PGQ8UW%3FSubscriptionId%3DAKIAILSHYYTFIVPWUY6Q%26tag%3Dduckduckgo-z-20%26linkCode%3Dxm2%26camp%3D2025%26creative%3D165953%26creativeASIN%3DB003PGQ8UW Very similar to the penny loafers, but without the heel and with a cleated underside. They are more comfortable for a lot of people because they are much less rigid, but this also means that they will not keep their shape long. I had the pair I linked to, and got about a year of use from them before the toes started to tear. The most popular driving loafers are Cole Haans:

• I would suggest keeping Sperry's or boat shoes as far away from your business casual wardrobe as you can. If you really like the look of boat shoes, camp mocs are their slightly-more-dressed-up cousin: http://www.sierratradingpost.com/ralph-lauren-footwear-henley-camp-mocs-for-men~p~64004/
  
  
• Of course, this being MFA, I think it's necessary that I recommend CDB at some point: http://www.amazon.com/Clarks-Originals-Desert-Taupe-Suede/dp/B000VWDZHM/ref=sr_1_1?ie=UTF8&qid=1328190823&sr=8-1 You know what they are, they'll work in just about any scenario. They may not be the most comfortable shoe in the world, though, and depending on the office, they may be too casual.
  
  
• If you want to get a little dressier, or you like the look of laces, try wingtips oxfords: http://www.allenedmonds.com/aeonline/producti_SF6105_1_40000000001_-1
  
  
• And finally, some nice suede bucks never go out of style, especially during s/s: http://www.orvis.com/store/product.aspx?pf_id=06L0&adv=127748&cm_mmc=plas-_-MensClothing-_-06L0-_-127748&kpid=06L0-02-07%26catargetid=1796447680&cagpspn=pla
  
  If comfort is really one of your main concerns, you will probably want to pick up some kind of gel sole to put in whatever shoe you want to wear. Also, loafers will need to be broken in to your foot. The best way to do this without hurting your feet is to get loafer socks, which shouldn't show at all.
