You will need to purchase a crank puller to remove the cranks from the square tapered bottom bracket spindle. You can find these at amazon.com, and I would recommend a Park tools brand (about $14.00, plus S&H).
As to replacing the front chainring, the stock chainring is a 38 tooth unit, staked onto the right-hand-side crank. You will actually need to get a smaller chainring to make pedaling easier for you.
You can do this, but it will entail some very judicious parts choices on your part. If you feel that this isn't something that you'd like to do yourself, you will probably want to take the trike to a COMPETENT and CUSTOMER SERVICE-oriented bike shop, and have them either change the cranks and chainrings, or install a 3-speed hub, like the newer trikes come with.
Another option would be to just buy one of the new trikes which do have the 3-speed hub installed, but I'd recommend asking the bike shop owner if it would be alright to try it out first.

They're called chainring bolts and they come in a few different lengths - through one, two or all three rings.
Hundreds of them on eBay cheap. eBay search "chainring nut" with "double" or "triple" as required. They also come in light alloys and colors.
Most use 5mm allen key or torx T-30, but not both.
They require a special tool to hold the rear (flat part) still while tightening the front. Chainring Nut Wrench Park CNW-2 or Shimano TL-F-Y13009700.
eBay search "chainring nut wrench"
A BikeShop can advise you further.

What exactly are you needing help with? Most bikes are just static frames with a bunch of aftermarket (Shimano, for example) stuff hung on them.
Except for proprietary frames or technologies, everything on a common bike is found on just about any other brand of bike and the individual components are usually documented at the individual manufacturers' websites.
Places like http://www.parktool.com/blog/repair-help document many of the repair and adjustment procedures.
Search Engines will find tons of How-to videos for assembly and adjustment if you just type in the basic question.
