I have 2 physical sites
2 DC in 1 site 1 GC
1 DC in 1 site 1GC

i need replication to be very quick, would i modify the DEFAULTIPSITELINK to do this? maybe set it to every 15 minutes? is there a downfall?

I also want each server to be able to replicate to and from each other do i need to create additional NTDS settings? what should the schedule be for all of them?

inter-site replication is instant, for intra site you need to setup the site replication cost as lowest as possible (may be 100 or 200) and replication interval to 15 mins. it will take the bandwidth but this is the fastest method

15 minutes is the lowest you can go via the GUI,  if you want to change intersite replication to be as quick as intrasite you can enable inter site change notification (ISCN)
Good overview and how to do it here  http://www.frickelsoft.net/blog/?p=145
So one interesting thing is that Ned on the AD team recently mentioned this
...see last paragraph...he would recommends turning it on
...and see my comment/response...I still think in very slow links I would not turn it on.  In your situation with a small AD and two sites it would be ok.
Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.
