Well, if the seals are your only worries, then you have no worries. Seals are easy, setting the timing is a giant pain in the ass. Having a friend is a good idea unless you determine that buying the special tool is worth it.
I kind of agree with the above poster about leaving the seals alone if they aren't leaking. I replaced my crank seal when I did the belt. It was not leaking before replacement, and ~40,000 miles later it started leaking pretty bad. Now I have that along with the burning oil issue. You think you're being preemptive and responsible, but may just be screwing yourself over. At least get quality seals if you do decide to replace them.
