Hi isatrader & KinsaleForex,
Besides the books you've already referenced, there's one that might escape your radar that's well worth a look at IMO called 
Marc Rivalland on Swing Trading Rivalland is nuts about P&F charts and devotes a whole section of his book to them. It's basic stuff comparted to Du Plessis' Definitive Guide, but his comments and observations are well worth reading nonetheless. Don't let that fact that it's aimed at swing traders put you off - there's plenty in there of interest for the day trader too.
You appear to be going down the DIY route regarding charting. There's a lot to be said for this and the ones you've produced look great to my eye. If you do go down the commercial route, tread carefully, as quite a lot of vendors offer P&F charts but don't fully understand them. The main issue tends to be the aspect ratio of the chart which needs to be 1 : 1 in order to correctly draw in 45 degree trend lines. Surprisingly, lots of software packages struggle to do this! 
If you need any help, dentist007 is a P&F buff and all round helpful bloke. You can find him and see examples of his charts on the 
Wallstreet1928 Analysis & live calls on FTSE,DAX,S&P...aimed to help New traders thread. If you can get hold of him (and I haven't seen him around for a while) the real expert when it comes to P&F and computers is 
DaveJB who's written some excellent articles for T2W on P&F - which you can find 
here.
