Welcome aboard, Jamie!
I think your ECU is the Magneti Marelli IAW 5AM, in which case Avanti Race Parts
http://www.avantiraceparts.co.uk/page.php?id=19can can reflash it with the Ducati Performance Termignoni map.
Alternatively, Neil at Cornerspeed
http://cornerspeed.co.uk/tuning.php can download a Rexxer map for either slip-on cans or a full system.
Both companies offer a postal service, so you just send them your ECU.
For posting pictures, you need to use a photo hosting site.
I use
www.postimages.org/signup.
Once you've uploaded your picture, you should be presented with these options...
Click on the blue 'copy' icon next to the 'hotlink for forums' address and paste it into your post.
If you preview the post before submitting it, the picture will appear in the preview if you've done it correctly.
As for the paddock stand, I had an S2R 1000, and the paddock stand is, I'm fairly certain, the same as for the S4R Testastretta, (I'm still using it on my 1100 Evo).
You've made a great choice of bike. I look forward to seeing your pictures and good luck with the exhaust hunt!
