Your in for a treat mate!
Went through my bookcase, and would recommend the following as good quality books/reads if you don't have them:
Philip Sugden - the complete Jack the Ripper
JtR - The Facts - Paul Begg (almost anything by Begg is worthwhile)
JtR - CSI Whitechapel - P Begg & J Bennett (this has recently been republished slightly differently as this:
https://www.amazon.co.uk/Jack-Ripper-John-G-Bennett/dp/023300520X/ref=sr_1_8?s=books&ie=UTF8&qid=1485191004&sr=1-8&keywords=jack+the+ripper+books & I've seen the new version in the works cheap. Really good CGI interpretations of the crime scenes.
The Complete & Essential JtR (Begg & Bennett again)
JtR Letters From Hell (explores masses of so called JtR letters) Evans & Skinner
JtR & the case for scotland yards prime suspect (Rob House) worthwhile if you're interested in Kosminski
Ripper Diary - The Inside Story - Linder, Morris & Skinner - there are other diary books (shirley harrison, paul feldman and others have written maybrick books) but the most impartial is this one. feldman, harrison & robert smith have an agenda imo.
The Trial of JtR - Euan Macphearson/JtR Unmasked - William Beadle - 2 good books on william bury, a potential suspect. I don't recommend many suspect books, but these are ace, and bury is worthy of consideration.
By Ear & Eyes - karyo Magellan - phenomenal read that like Tom Wescott is great for those with a good overview of the case, and want something a little more detailed. This is a forensic examination of the witnesses, and the injuries sutained. His treatment of Israel Schwartz is brutal, and very worthy as a result.
The secret of prisoner 1167 - James Tully - narrates how a psycopath escaped from broadmoor in early 1888, was in london through summer but not caught, and then not heard of until the 20th century, when elderly he handed himself in. quite gripping, worthy of reading.
Jtr Scotland Yard Investigates - Evans & Rumbelow.
Batshit mental books - they all love jack by bruce robinson is nuts! as is JtR british intelligence agent by tom slemen. Naming JtR by russell edwards is pure unsubstantiated crap written by someone with a messiah complex.
Avoid anything royal conspiracy, except maybe stephen knights book that has a tragic backstory behind it.
