Hmmm.. as far as the P.U.L.S.E. tabs go.. I am not aware of any.. I'll do some digging and ask a few friends if they know of any.
If you have the tabs for the standard recordings (the ones on here), with a little experimentation and improvization you should be able to get moderately close to what you want.
Hardware wise.....First use the Jackhammer to break up the Samick... oopssss, did I type that..kidding..
Does your Squire have the standard pickup arrangement? Assuming it does (S S S) you may be able to get close but you will never equal Dave's tone without spending a few dollars ( or marks, or pfennigs or euro's or whatever) .
You'll want to be on the lead position on your selector switch (pickup closest to the neck) with clean tone. If you have any effects pedals you will want a bit of compression and chorus.
What type of amp are you using? That will have an effect as well. Again, you will want your amp set fairly clean. I set my Pre about 6 and my post about 3 for most of my PF stuff. Of course, Master Volume at 11.
I am currently using a Digitech RP200A effects processor. What I like about it is the fact that I can run up to 11 effects simultaneously out of one unit, setting each effect independantly. It will also model amps and cabinets so no matter what type of guitar, pickup, amp combo you are using, you can get the sound you want.
If you are limited on funds and want to make a cheap guitar sound a lot better.. and a good guitar absoutely wail....look into it.
