I used to play closed games such as KIA/KID/Pirc and I studied endgames. Here lately, I’ve been working on tactics which is why I decided to change openings to a more tactical type to reinforce my tactical studies.  If I survived to the endgame I usually won but had problems during the opening and middle phase.  I realized tactics is probably my weakest area and if I want to improve I need to rectify that.   

 

Well, so far, it looks like the Evans gambit is the winner and obviously we don’t know if anyone else will reply so, I’ll start on the Evans and check out the Two knight’s with 4)Ng5 which MNb suggested. Any other possibilities? What would be the best book to help me learn the Evans? I’d prefer one that is more theory and understanding than a datadump of game notations. Any suggestions to what I should look out for or be prepared for when playing this such as traps, most common defense, etc. You guys know more than I do and this will be my first look at the Evans so any advice would be appreciated.   

 

Thanks again to everyone for your opinions. Your comments have helped me in this decision.

I´ll second what TopNotch says, but if you want my opinion of the openings you listed there...

If I was put in a timewarp back to my junior chess days when I was an up and coming, I experimented with the max lange - it is interesting for sure, but I would not recommend it as the basis for a repertoire. I also gave the Kings gambit an outing before moving on to the good old Lopez, and here too the comment applies - interesting, but not for keeps.

IF you insist on gambit play, and I respect that romantic approach to chess, then I would seriously look at the Evans gambit. I believe it is sound enough. There may be problems getting an advantage in some key lines, but at the level you are at if you know it well you will pick up lots of points as I suspect your opponents will simply not know the best defences.
Bear in mind you need something against the 2 Knights - for that maybe look at another thread somewhere here about 4.Ng5!? where Nigel Short is in full sweeping opinion mode.

Max Lange and Evans: concentrate on 1.e4 e5 2.Nf3 Nc6 3.Bc4 (you might consider 3.d4 as well, though it rules out the Evans) Nf6 4.d4 exd4 5.o-o/5.e5 first. They do not offer much. White's best options are 4.Ng5 and 4.d3 and they might not appeal to you.
Göring: don't do it. I have played it myself, but 4...d5 and 4...Nge7 are much less fun.
King's Gambit: by yourself the recent Johansson book.

The move order 2.d4 is interesting, it guarantees an open game with lively piece play. After 2...exd4 not 3.c3 because of d5 and Nge7 again and also because of 3...Qe7. 3.Nf3 Bb4+ also has its problems. So 3.Bc4
a) 3...Nc6 4.Nf3 and Nf6 will be the big problem again.
b) 3...Nc6 4.Nf3 Bc5 5.o-o does not transpose, as d6 is stronger than Nf6. So 5.c3 Nf6 6.o-o, which is an offshoot of the Max Lange.
c) 3...Nf6 4.Nf3 is the Steinitz Variation of the Petrov; 4.Bc4 is the Urussov Gambit, when Nc6 is once again best.
d) 3...Bc5 4.c3!?
e) 3...Bb4+ 4.c3 dxc3 4.Nxc3 and White has still the option to play the other knight to e2.
f) 3...d6 4.Nf3 is likely to transpose to the Philidor. An interesting option is 4.Qxd4 Nc6 5.Qe3, which is an obscure sideline of the Centre Game.
