dt, yes you can request further interviews, for example to clear up ambiguity, change your version of events etc but to refuse to say anything during an interview that you requested is going to be some what difficult (and odd). The police may wish to further interview you but then its up to you what you say, if anything. A record of any interview may be used in evidence in court.
"looking back at it i wish i said no comment due to all the online post that i have read".
Just to add to the excellent post by New Judge, you've really got to know what you are doing giving a no-comment interview, get it wrong and it could cause you major problems. There are several situations where a no-comment interview is good advice such as police currently not in possession of admissible evidence or police refusing to disclose info to solicitor prior to accused being interviewed etc etc but you will need quality advice. Certain conditions allow police to use whats known as 'Special Warnings' during questioning and refusal to answer will likely result in a court drawing an inference from that...risky business, so always seek proper legal advice.
I've often heard people say to coppers with a stupid grin, "I'll just go no-comment mate", but a no-comment interview can make life a lot easier for the officers, and usually the prosecution.
Obviously, speak to your new lawyer who can advise you having assessed all the facts of this case.
