Hi ladies!  Need help here!  I LOVE LOVE LOVE pictures, but am completely a newbie when it comes to photography.  I have a friend who is getting married at the end of the month and can't afford a photographer, so she asked me to do her pictures.  I've fiddled around a bit and done some outdoor family portraits, etc. for friends that I've posted on FB...which is what she has seen and said she is impressed with.  However, I hardly know what I am doing with my camera...I feel like I have been just lucky capturing what I have been able to, at this point.  Needless to say, the pressure I am putting on myself to do a crash-course learn of what I need to know to do some decent pics for her wedding is making me CRAZY.  I have a Nikon D40x that I inherited from my brother.  I really only know how to use it on auto.  I have the basic AF-S NIKKOR 18-55mm 3.5-5.6G II ED lens.  Since she is getting married in the evening and I HATE the flash, someone suggested I get a better portrait lens - a 50 mm - F/1.8?  Can anyone direct me to specifically what I should purchase that doesn't require any manual focusing, etc. and something that I could use decent without a whole lot of knowledge on my part?  Oh, and budget is a factor  - I don't want to invest a ton of $.  ANY help - in plain English :-) would be appreciated!
