Welcome to the STD forum. Congratulations on being conscientious about your partner's health in relation to your HSV-1 infection. But you really should have no worries.
First, "another practitioner" -- by whom I assume you mean Grace's reply on the herpes community forum -- is exactly right. HSV doesn't travel through the body to sites other than the region where it was aquired. Assuming your oral HSV-1 infection began in childhood, as for most people, then you can be sure you do not have a genital area infection.
THe information you quote from the U of Maryland website also is correct, but with one clarification. Although the symptoms of HSV-1 or HSV-2 are identical, either during the initial infection or a recurrent outbreak, there is a crucial difference between them: HSV-2 generally causes much more frequent outbreaks and has asymptomatic shedding (i.e. infectious periods without symptoms) than HSV-1. Your oral herpes outbreak frequency of 1-2 times a year is typical. In contrast, most people with symptomatic genital herpes due to HSV-2 have 4-8 outbreaks per year.
To your specific questions:
1,2) Almost certainly you don't have a genital infection and cannot transmit your infection to your partner except by kissing or performing oral sex on him. The presence or absence of a non-herpes genital area rash or irritation will make no difference.
3) By far the highest risk for neonatal (newborn) herpes occurs when the mother acquires a new genital HSV infection in the last 2-3 months of pregnancy. Transmission to the baby is very rare when the mother has longstanding herpes, even a genital infection; the mom's antibodies against HSV are highly protective (although not 100%) for the baby. In your case, the main risk is if you have an oral herpes outbreak before the baby is a few weeks old -- so if and when you have a child, you'll need to be alert to recurrent oral herpes and avoid kissing the baby (and use careful hygiene) until the outbreak heals.
To be super safe, if and when you are pregnant, tell your obstetrician about your oral herpes -- and the baby's pediatrician following birth. But the overall risk is extremely low; after all, half of all women giving birth have HSV-1, and yet there are only a few hundred cases of neonatal herpes every year in the US.
For all these reasons, the main transmission risk here is to your sex partner, and will come not from intercourse but from kissing and performing oral sex on him. The risk will be low if you are careful to avoid such contact when having an outbreak -- but it could occur in the absence of an outbreak. On the other hand, because of the lower recurrence frequency and other factors, genital herpes due to HSV-1 is not usually a big deal, so this isn't something he and you should be especially worried about. In case you are interested, here is a thread that goes into detail about genital HSV-1 infections:

I hope this helps. Best wishes-- HHH, MD
