If you opt for blacktop, it *may* be possible to overaly the existing, but that's a decision that can only be taken once the existing surface has been assessed. Further, blacktop on a "steep" slope can be tricky unless done by a genuinely competent contractor....mind you, concrete on a slope is no tickle of a job, either!
Steps, being awkward sods, are very difficult to construct using blacktop - you'll need to consider an alternative and modular paving is the simplest option (so: flag-and-brick or block paver steps).
To eliminate a hump and thereby prevent grounding, a site survey of surface levels is needed. That's the only sure way to determine how much can be shaved off to ease the hump - the usual guidance is nothing more than 150mm over a 3m span.
In short, without assessing the site, it's impossible to provide you with anything other than generic phrases. For a worthwhile spec, a designber or engineer needs to be familiar with teh site and it's environment.
