Yes!!! It works just fine.  I use 2 9" units on the bow. Fished a 7" for almost 3yrs prior.  The 9" is a perfect size. Only downfall you loose the ability to network units unless you get a data hub since they only have 1 data port opposed to the 10 and 12s have 2. You'll be fine. 

10lb and above should be fine as long as you're fishing with sharp hooks.  If it's dull it doesn't matter what size line you use.  Hook size is hook size.  If it's sharp it's going to penetrate much easier then if it was dull. But I rarely ever use anything larger then a 4/0 depending on brand.

you could get a regular binder and some freezer gallon bags.  Or seperate you worms by technique and put them in gallon bags that way.  Then when you need a dropshot worm, grab the dropshot bag and find your worm or what ever you're looking for.

I would order from West Marine and use their West Systems Epoxy 105 Resin as well as the 205 hardner either slow or fast cure depending on how long you want to wait.  For coating and sealing if you're not in a rush, go with the slow cure, and for taping I'd use the fast.  So short answer, order a larger amount of 105 resin and order 1 of each of the smaller hardening agents (205).  Follow the guidelines, if you mix this stuff too hot, it will smoke and could ignite flamable materials if you try and throw it away while it's curing (if mixed too hot)  When it says 5:1, normally the resin is in a bigger container and they have pumps available for them that accurately dispense the proper amount.  1 pump of each gives you the right ratio.  I'd coat one side and let it rest.  Then coat the other after that side has cured and dried. 

I would put a mono backing on first and then spool up your braid.    Depending on what size braid your fishing I try and get about 100-125yrds on each reel and fill my backing acordingly so the reel is full.  Never have a problem with it slipping.  If you want a full spool, well you're gonna have to put some tape, electrical or some kind of adhesive tape to give the braid something to grip.

was this a used reel?  If it is and you are going to take it apart, make sure you keep track of each piece and where it went since you say you're new to bait casters.  Now if it is a used reel, sounds like the drag is froze up.  Open the reel, and the drag washers are located inside the main gear.  You will have both metal and fiber washers. Clean and polish the metal washers, these should be stainless.Try and find/order new drag washers for that reel if you can.  Be careful not to damage the fiber washers if you don't have replacements, If they are just stuck to the metal and you can pull the drag apart, use some really fine sandpaper or the smoother side of a knife sharpening stone and lightly rub while wet with water.  The idea is to knock off any irregular features on the washer.  Then, once dry, like Tywithay said, use some drag grease.  This would be lightly coating and I mean lightly...like a film of drag grease on the fiber washers only.  If you have the metal washers clean and polished, this will solve your problem.  If you are worried you might not get it right, I would take it to a service center or shop that does this and pay the $8-15 to have them clean the reel and replace the drag....less any parts they have to add.  Hope this helps.
