Looks Great!! Nothing too tough on that puppy to fix at all!! Is that part on the vertical which is chunked out foam with glass over it??
As far as stripping the paint....Ye-Ole Sandpaper...

(If your careful..a DA sander comes in Really handy for this process!!)
As far as fixing the cracks, chips and delams:
First you'll want to identify the resin used in construction of the fuse (ie: Epoxy, Vinyl Ester or Polyester)...You will need to repair the fuse with the same material it's made of...You can't mix-match resins..Epoxy is not compatible with polyester and the repairs will not hold up and vice versa...
With a little experience..Vinyl Ester and Polyester are pretty easy to differentiate from Epoxy due to the Styrene odor present (ie: New Boat Smell)...You can usually smell them and tell weather it's polyester based resin or not (Wierd Huh)...If the fuse is old enough that the styrene odor has gone away...A light scuffing of the fiberglass with sandpaper will usually rejuvenate the odor enough to tell...
You want to remove any of the "Bad Glass" via cutting, sanding or grinding...Ultimately you want to remove as little material as possible..But it's important to get all the bad stuff out of there...If it's "white, loose or cracked" it needs go bye-bye before you go any further...Patching over a bad spot will result in a weak repair...
In the case of a "crack" you should stop drill at the end point of the crack prior to grinding...This will relieve stress and help ensure the crack will not go any further (Just like working with Aluminum)...
Then you want to "scarf" (taper) the surrounding fiberglass so that your repair glass can "feather" into it...You'll start with a smaller patch and then each additional patch will be slightly larger as to eventually blend into the parent material as necessary...How may layers will depend on the thickness of the original laminate and the material used for repair...(Probably at least three layers of .75oz cloth )
Aside from very small cosmetic type "dings"...Attempting to repair with just resin is not good...Fiberglass resin without cloth it has no structural value and will be weak...To fill a crack with resin only will result in a substandard repair which will be prone to failure...Also...Attempting to glass over a crack or delaminated area is no better and will be prone to fail...You must remove the bad material first...
If your planning to repaint the whole Airplane...I'd suggest first stripping the paint completely before you do any glass work...Paint can hide fiberglass damage...Once it's completely stripped then you can assess your airframe and put a game plan together for the necessary repairs...
It should be a fun little project!! If you have any questions or need any help just Hollar!! If it's more than you wish to tackle...Bring it to me and I'll take care of the glass stuff for a small fee (you let me fly her once or twice!!

Here are a couple of links which may be useful?? :

Attached is a photo of some tools that make life much easier when doing this sort of stuff!! (note: forgot safety glasses..

)
Note: I disagree with the pictures of the fiberglass patch's as they are in reverse order...You first start with the smallest diameter patch and go larger as you work your way out...
