well everyone has some good advise. As already said, expierment with differant things. I personally would not suggest progressive fork spring, unless you are shorter. I have expierence with thease, they are ok for the street, but not realy for off road, thats probably why they are the same spring for a vn1100 cruizer.
But some have them and swear its the best thing since suggerd cornflakes
If you are remotely even attempting offroading, the forkbrace makes a huge difference in the way your front end handles.
And just as a note the stock fork oil is 10wt. The rear end is ok for most it definatly outdoes the stock front end. So as you assumed the front needs the work first. Then after you start jumping doubles a new shock might be in order
