Almost started with sweave

Question

my question may be less general than the name suggests. I am running R on Mac OS X with a MySQL database to store data. I have been working with Komodo / Sciviews-R for a while. Recently, I had a need to create automatically generated reports and view Sweave. I believe StatET / Eclipse is the "standard" solution for Sweavers.

1) Can I switch from Komodo to StatET Eclipse? I tried Statet before, but chose Komodo over StatET because I liked calltip / autosuggest and the more convenient configuration from Komodo.

2) What is the smart workflow for creating sweave files? I usually develop my R code first, and then take care of it later. I just found out today that there is one file in Sweave that contains the R code and the latex code right away, and a .tex document is created from this file. While the sample files look comfortable and cannot imagine how to enter my 250+ lines of R code into the file and mix it with Latex.

Is it possible to simply enter the qplot () and ggplot () operators in such a document and somehow run functions such as connecting to the database and intermediate results?

Or is it just a matter of using a combination of Latex and R?

thanks for any suggestions, tips, links and back to the roots of screams ...

Put any text I want before my table here, maybe with a \Sexpr{print(variable)} named variable

<<label=myTable, result=Tex>>= 
myTable<-dataframe(...)
print(xtable(mytable,...),...)

Any text I want before my figure
<label=myplot, result=figure>>=

I am on a Mac and I suggest TextMate if you played softly and emacs / ess if you are really defiant. I use vim and the R command line, but emacs / ess works best for most. If you have been in this for a long time, I doubt that you will regret studying emacs / ess for R, Sweave and LaTeX.
