Default [Q] Help with rooting P1000L with Gingerbread 2.3.6

I have the Galaxy Tab P1000L
I been trying to root it with Superoneclick and with DoomLord Zergrush, I keep failing all attempts, as I did research on this, I found out some info that says it is not possibe to root Gingerbread 2.3.6 (what I have) and that I need to dowgrade to 2.3.5 or to froyo (which is it?) , but SamMobile does not have Froyo available for download anymore...
So basically, I need to know how to root 2.3.6, main reason is I want to be able to change my Tab's HotSpot channel, and I read that this is only possible on a rooted GTab.
Thanks a lot for any help on this, I am new to Android, so trying to learn as much as I can.
( Secondary question: On a quick note, is it possible to upgrade to HoneyComb/is it worth it?)

Looks like I posted in wrong area, please delete.
