Hi ammandel,
i have the same Canon in the European version called EOS50D.
After shooting some pictures you will get used to all the possible settings.
I still have to go to a course but i getting some progress in my shooting capabilities.
The 18-200 is a good travel lense.
For macro and close upt you canbetter buy a good macro lens.
I'm using the Sigma 105 2,8 EX 1:1 MACRO.
Just an example of a sculpture my wife made called "mother and child"
And a example of my white also with the 105 MACRO
Please share some pictures with us
