Hello and welcome to the forum.
You ask some good questions and I will try to answer them for you below.
First, COPD is a common cause of pulmonary hypertension but it is a very UNCOMMON cause of severe pulmonary hypertension. In other words, the vast majority of patients with COPD are much more "limited" in terms of breathing, other symptoms, etc because of the effects of the COPD on their lungs even when mild pulmonary hypertension (usually the rule) is present. Having said that, in a minority of cases, the pulmonary hypertension that develops over time (due to low oxygen levels, etc from the COPD) can occasionally be severe. Thus, if your symptoms have changed or there is concern that you might have severe PH, the only way to truly diagnose it appropriately is with a right heart catheterization procedure. Thus, to answer your second question first, you first need to find out if you even have PH (echo is not reliable enough). And, if you have it, how severe it is. If it is mild, it typically stays relatively mild but in some cases it could slowly progress.
Now, to answer your first question, if you have "severe" pulmonary hypertension, then general anesthesia can sometime be dicey and should be performed by experienced cardiac anesthesiologists who understand the potential issues/complications in the PH patient. I'm not going to go into detail about the specifics. If you only have relatively mild PH, the PH will not be an issue with anesthesia.
Finally, your final question is a good one as well. Generally speaking, those who have pulmonary hypertension in addition to their COPD are likely to have a worse prognosis than those without pulmonary hypertension. However, these data are very much skewed towards those with severe PH (not the slightly elevated pressures that frequently accompany COPD). So dont beat yourself up over this even if you have mild PH. If you do have PH (again, must be confirmed by cath), and your oxygen levels run low (either at rest or with exertion), then where your oxygen as much as possible as the pulmonary arteries (and the right ventricle) LOVE oxygen.
Glad to hear that you will be seeing a PH specialist. If they disagree with any of the above, please let me know and we will find you another "specialist"
Good luck.
