Your situation requires a detailed private consultation with an experienced attorney in order to answer any of your questions. If you want to minimize the negative consequences then you need such help. No response you could possibly get on the Internet will serve as a substitute.
You should ask the attorney who represented/represents you on the charge for which you got house arrest. No one hear is familiar with the facts and circumstances of your case.
In order to really get a good answer, you need to sit with an attorney. I would have many questions as there are many issue intertwined here.
This is not intended as individual legal advice and there is no attorney client relationship established by this answer. It is advisable that you seek individualized legal assistance. This is not a substitute for hiring an attorney.
There is no easy answer here. You need an attorney to dig through the specifics of your sentences. Typically once a sentence of house arrest is assigned, time served after the fact will not count. Your time in jail was because of new criminal charges not the original charge or which you received house arrest. I would contact an attorney asap.
