I am wondering if I am able to get some pointers and thoughts/advice please

A brief summary before my query :
arrived on student : Oct 2007 - Oct 2010
Renewed on student : Oct 2010 - Oct 2013
Renewed student : Oct 2013 - Oct 2014
FLR lodged on Oct 2014
Since then FLR has been refused with appeal rights, then appealed gone to FTT, then to UTT and now currently on COA - awaiting a response.
There is no period stayed out of country, all documents are with the HO (including PP - currently expired) : my 10 years is completed.
LIUK T done
and I qualify for the 10 year LR route - what are my options?
is there is a risk in going for premium without my originals? and also expired PP?
any advice and recommendations?
