If you have msn add me I lived there for 2 years I can answer any questions you may have
Hotels in the City Center:
Marriot Hotel:
Very good location, right in the city center, includes a gym, swimming pool. Near a few restraunts and bars.
Travel Inn:
Just off the fly-over, not quite a good area (in terms of both local ammenities and also the surrouding area)
The Docks:
There are numerous hotels on the docks, but they tend to be both gradeous and expensive. However, if you've got unlimited money

then check these out. There are also some very nice restruants and bars, as well as docks and the ferry across the mersey (and yes they do play that song on the boats as you cross -- or at least they used to).
Records Shops:
In the city center, the 3 main record shops are HMV (2 stories, lots of DVDs and Videos, good rock/metal section, but not a huge classical selection). Virign Megastore, (2 stores, good rock/metal and specific OST/Classical/Jazz room, which is isolated from the rest on the top floor, a tad more expensive than HMV in most cases, but you can get some great offers in there at times) and MusicZone (this is the cheapest of the lot, but selection is limited, and you have to be prepared to hunt around for what you may want). There are alot of independant specialist record stores, like Probe, etc. But I'll let you discover these as I had to.
In the way of Bookshops, your talking Waterstones, WH Smiths, and a few independant stores. The Waterstones is quite big (3 stories) and has a Costa Coffee in there, so you can go in read a book in the coffee shop and but the book back

ahem, I never actually did that for the record. WH Smith is just like any other WHSmith, 2 stories, alot of local books by local authors in there, that you perhaps wouldn't find in other book stores. There are also independant book sellers in St. John's Shopping Center (the stand out destinctly for the inordinate number of shoe shops

).
A Good Pub:
The Ship & Mitre is a favorite of myself and a friend of mine, its quite has a selection of "uncommon" lagers/bitters/ciders, and is generally quite nice inside. Its a little way out, if you head for the Wallasey Tunnel its right around there. The Swan (on Wood St.) is another quite, rock type place, be repared however for the odd funny look from bikers that sit near the door.

For live music, there are quite a few bars that put on local bands, but if your after something more well known, checks out the Carling Academy and the Barfly, these are located near Lime St. station, and on Seal St. respectively. For local bands, your going to want to check out Zanzibars on Seal St. And Hev n' Hell, these all have local bands on most nites, not sure on prices of lager. The Cavern also has live bands on, check before you so. If your going in October the students will all be back, and hence the student bars will be open, the Student Guild (AKA Liverpool Academy, but note NOT the Carling Academy) is ??1.20 for Carling, which is reasonble, it also has pool tables and is generally quite quiet during the day. Even at nite there is no loud music in there.
Places To See:
1. The Albert Docks.
2. The Lamb Banana.
3. Liverpool Museum
4. Beatles Exeperience
5. Matthew St. (Home to tons of bars + Cavern)
6. The Cavern (if your a fan check it out, even tho its not the original Cavern, which got knocked down).
7. Quiggans (Indoor shops, all independant traders, selling all sorts of stuff, its DEFINATELY worth a visit).
I hope this has been helpful, and to summarise here's a list of streets you should ask for if you get lost (they all have good stuff to do)
Matthew St.
Slater St.
Wood St.
Seal St.
The Cavern
Quiggans
