So when I reach level 9 I spend my skill points that I gained from level 1 to level 9 ?
And then start all over again ?
Since you are a regular member of this board

:
The gap of nine that everyone talks about is the threshold after which there is no further gain in increasing the gap. But leveling with such a high gap is very, very, very painful, so it is usually built up at certain points to specifically farm SP (for example at level 16 for farming at the stronghold) and gets closed or reduced after the targeted amount of sp is farmed. So don't get too hung up on it.
I personally wouldn't follow the course you describe but instead keep a small gap you feel comfortable with, maybe even closing the gap completely at the most important points (level 20, 30, etc.) and just rebuild or increase the gap, throwing in some actual farming (with items you decked out to the max to make up for your weak state), if your sp gain is insufficient. One of the reasons for this is the dependence of euro characters on their mastery levels when it comes to the armor they can wear. Otherwise you'd have sucky armor every time you really need it (and as a rogue you need what you can get) and that is when you are already very weak because your skills are seven or eight levels behind.
Did you use the skill calculator yet to find out how much SP you will need?
*edit*
Just a little example:
Skillpoints needed to get all rogue skills at level 60 according to the calculator: 80.062
SP Gain from 1-60:
3 level gap: 66.813
4 level gap: 83.930
So (if the numbers supplied in the spreadsheet are correct) you need a gap of 3-4 levels to become a fully skilled rogue proficient in both daggers and crossbow.
