quantmod/Rmetrics-timeSeries and RQuantLib/Rmetrics-fOptions ?

Hi guys,
I'm a no-pro option trader and I'm learning to use R + packages that can
help me to do better analysis and quit spreadsheets.
I bought the book "R in a Nutshell" and booked the on-line classes from
statistics.com on R language  (introduction classes will start on 20 of
May).

There are some doubts on which I need some help, I'm going to spent a lot of
time on learning steeps and R has a lot of packages for time series analysis
and options, the point is on which packages it's better to stay focused ?
a. quantmod or timeSeries/Rmetrics ?
b. RQuantLib or fOptions/Rmetrics ?
c. Do you recommend eBooks from Rmetrics ?

Thanks very much
Massimo
