how to deal with NEW domain name? (backlinkging & hosting question)

I have a new domain name. I heard you shouldn't blast away backlinks to brand new domain name. If that is so, how much backlinking is safe? 1 backlink a day? 10? 100?

Also, I plan to put this domain name on a SHARED Bluehost hosting account where I host my aged domains that I blast tons of backlinks to. If Google decides to de-index my NEW domain name, I'm worried they will also kill my other older sites hosted on the same account. So should I have a separate hosting?

Don't worry about the amount per say, just do not make it look spammy! a couple of hundred links per day is normal, as viral websites get that straight away, but no matter how viral a website is, it won't get 10's of thousands of backlinks like you could get by using automating softwares .. Keep it 'real', use unique content and you should be fine.

Sorry, i cannot help you with the hosting problem!
