Didn't read your response until now.
I want to burn less calories for bulking up and lifting weights, which has a higher priority now due to my available for working out, timing, injuries, other circumstances, etc. I don't have enough time to cook food, eat, etc.
How often should I check my resting HR and blood pressure? What's ideal HR for long term health?
A healthy blood pressure is a systolic of 90-120, and diastolic of 60-80. Ideally you probably want your resting heart rate to be 60 BPM or lower, but 70 or lower would be alright. One thing to keep in mind is that to a degree these are just arbitary numbers.
Like you said, it's a matter of long term health, so you don't need to measure your blood pressure or RHR all that often. Unless your blood pressure or RHR is of particular concern (I.e. you suffered from hypertension in the past, or you use it as a way to monitor whether you're over training) once every couple or few months should be fine. Unless you have the money & inclination to buy a machine that measures BP and RHR (I forgot the name of the machine), then you can measure as often as you like.
But on to what's really imporant: don't make excuses about diet. You can always eat more, even if it's just simple things like steak, milk, fresh fruit and vegetables, eggs, smoothies (a blender, protein powder, milk, some kind of frozen fruit, some ice cubes, maybe peanut butter, and you've got something good), almonds and peanutbutter. A person could live off (and be quite healthy) what's listed above, and never spend more than 10 minutes cooking (Steak takes the longest, but you only need to sear the outside of a steak.
You just don't want to be doing ridiculous amounts of cardio while trying to gain weight. Try a couple steady state workouts a week of about 30 minutes with moderate intensity. It can be whatever you like, running, swimming, cycling, doesn't matter, as long as the time and intensity is appropriate. In addition add 1-2 higher intensity workouts, either more steady state or some kind of intervals. The intervals can be done with the same sort of exercises you do for steady state, or can be stuff like prowler work, barbell circuits, strongman type stuff etc.
