Current Gen 2 iPod Touch on new Macbook Pro - will restore work?

Question

I backed up my ipod touch on the new macbook pro computer (right clicked on my ipod on the left nav in iTunes).
I want to (1) update my ipod touch from 3.1.2 to the new 4.2 OS and (2) use my new macbook pro from this point forward.
My question, if I do a restore and select the backup, will all my apps (and app data), safari bookmarks and all info on my ipod touch be restored properly? I am scared that I will lose all my information.
I previously synced my ipod touch on the older powerbook.
Anyways, your advice is greatly appreciated!!

Answer 1

My ipod touch was initially "connected" with the powerbook. When I did a sync on the powerbook (old computer), a bakup was created. In iTunes, I was able to see a list of my apps on the left column (sync apps) next to the right column, that showed what was on the ipod touch.
On the new computer, macbook pro, after I backup the ipod touch via right clicking the ipod touch on the left left pane.... I do not see my apps show under the sync apps column.
When I check the box to sync apps, under the apps section, i get a message saying, "Are you sure you want to syn apps? All existing apps and their data on the ipod touch will be replaced with apps from this iTunes library". From the looks of it, none of my apps added onto the library of the macbook pro, as the left column, sync apps, is empty.
I noticed too, when i backed up the ipod touch on the powerbook, i saw my apps on the status pane show... and eventually show up on the sync apps column on the left. During the backup to the macbook pro, I didn't see that happen.
Backstory: I got the ipod touch as a present, started using it through my powerbook. I haven't updated it much on the powerbook for a long long time. I got more apps, added bookmarks and used the ipod touch frequently, without really attaching it to the powerbook. Only maybe one time last year to upgrade to 3.1.2 os. Around that time, powerbook was super super slow and having problems.
Sometime spring/summer last year, I got a new powerbook and haven't had a chance to connect the ipod touch to it until now. I had trouble syncing/transferring my ical, iphotos and itunes (between the powerbook and macbook pro)... but eventually added what I needed for the most part, without adding older stuff i didn't need anymore - pretty much manually. i lived with not having my playlist on itunes and redoing my events in ical. luckily, i have a iphoto library manager, so my photos albums are intact the way i'm comfortable managing them.
anyways, i want to update the ipod touch to the latest os 4.something. and start using this macbook pro as the go to computer, as i won't be touching the powerbook much.
I care more for the apps and the apps' data, ipod touch safari bookmarks... photos and music i can redo again, as both are different between the powerbook and macbook pro anyways.
the macbook pro is authorized, as with the older powerbook.
i think the reason apps don't bakup inot the macbook pro, is because it's somehow still associated to the powerbook. the contents on the ipod touch are more current than what is on the macbook pro, as regards to apps and apps info and bookmarks.
Help! Please.
