First - I think your kit is great - and you'll grow into it with ease. That 100mm f2.8 will amaze you with sharp, poppy images. A flash is IMHO a boon to any photographer - it amazing how many situations need more than the built in unit. Enjoy your new kit!
Just to put in a bit of extra info on netiquette and reading
UPPER CASE vs
Mixed Case vs
lower case.
Netiquette regards all caps as shouting - its been around for a long time, and probably stems from the fact that when we read we don't read the individual letters but the shape of the words and key letters (every misread a word? Its probably got the same key letters in the same place as the other word).
The combination of risers and descenders make reading easier according to
research from the 1930s onward - its pattern recognition. Lower case text is read faster than upper case text.
There is also evidence we read what we are used to faster - most of us read lower case text more often. You can train yourself to read UPPPER CASE faster if you read lots of it
MiXinG CAseS is AlSo dIffIculT to REaD - you have to read each letter
But there are papers showing its the placement of letters in a word that lead to its recognition.
Have a read of the following for starters (the last one has lots of references):
Just my two bits worth......
