How can this program be improved?

Hello All Marketo people.....a detailed look is required here....!!
How can I improve this program?
We send emails on a regular basis with new content + link but same target audience.......
Question 1)
Do I need a program to put all email blasts (mailbox sign) into this brown colored program folder? OR do I keep these emails just in a campaign folder?
If you look at this screenshot 1 (above) --- what can I do to improve this program? Success is not measured here / leads are not being sent to sales team as I don't know what to send them? See below my questions?
- There is no program status showing up? Why does it show 0? Is it because its not set up ? Smart campaigns are missing yes!
- There are no smart campaigns to move the leads through statuses so should I include these?
- Set up has nothing ? We want to track costs / analytics / etc...
- Should I use tags in this program? Tags are not set up for a program like this? Advantage of tags?
- Should I set this up as a separate program (brown folder) and then add the email in the brown folder>> OR keep adding email blasts (mailbox icon) to the same program?
- How do I measure analytics in this program - overall analytics?
- How do I see if new people were added to Marketo via these emails?
- How do I see which ones converted to an MQL? Any reporting you can suggest?

Question 2)
I send the same email to three regions...........Australia / Europe / US and Canada-
Footer is different / From Email Name and Email Address is different AND signature of the sales owner is different for these three regions.....how does segmentation work in this?
Do I need to create these segments first in database section? The geo territory is not defined well I see mostly AU is defined well.

If something is not clear I can in next comment.
