<changing margins for clarity>

i'm trying to figure out how exactly to replace hsrp with vrrp and glbp
<command for command>, but i know that there are big difference with vrrp and
glbp with regards to the ip address used for the virtual gateway. from my
readings, vrrp actually uses the ip address of the interface for the master
router as opposed to a completely virtual address as with hsrp....so there
goes (r1 is active and R2 is standby)

HSRP R1 VRRP R1 GLBP R1
int e0/0 int e0/0 int e0/0
ip add 1.1.1.1/24 ip add 1.1.1.1/24 ip add 1.1.1.1/24
standby 1 ip 1.1.1.254 vrrp ip 1.1.1.1<?> glbp 1 ip 1.1.1.254
standby 1 preempt vrrp 1 preempt glbp 1 preempt
standby 1 priority 115 vrrp 1 priority 115 glbp 1 priority 115
standby 1 track int s0/0 n/a glbp 1 weighting
track 1

HSRP R2 VRRP R2 GLBP R2
int e0/0 int e0/0 int e0/0
ip add 1.1.1.2/24 ip add 1.1.1.2/24 ip add 1.1.1.2/24
standby 1 ip 1.1.1.254 vrrp 1 ip 1.1.1.1 glbp 1 ip 1.1.1.254
standby 1 preempt vrrp 1 preempt glbp 1 preempt
standby 1 priority 110 vrrp 1 pri 110 glbp 1 priority 110

so, my question is - are the virtual ip address above correct when compared to
hsrp (does vrrp use the interface of the master instead of a virtual
on........does glbp use a virtual the same way that hsrp does?)
and
does vrrp and glbp decrement the active router the same way that hsrp does
<minus 10>?
am i correct in noticing that there is no way to track an inteface w/ vrry?
