On the HR thing, those machines can be notoriously inaccurate. I only get a HR that matches the one on my monitor about half the time.

Don't rely on charts at the gym or formulas to tell you what your HR should be -- HRs are too individual for that.
I definitely wouldn't try to slow it down, though I would try to make it longer as you get more fit. Also, maybe start trying intervals of 30 seconds very hard/30 second very easy as an alternative way to build your cardio fitness.
