The PLA doesn't have unlimited budget, and must choose which areas to modernize carefully.
If I were setting the top 5 priorities, it'd look something like this:
1) Build an effective nuclear secondary (retailatory) strike capability. This can be done within 10 years, through a combination of improved road-mobile ICBM's and SSBN's. At minimum the PLAN should operate a fleet of 3-4 modern SSBN's. I'd prefer around 8.
Having an effective secondary strike capability would defend the PRC from nuclear blackmail. This is very important as more nations are becoming nuclear powers.
2) Fund R&D for better missile defense - combination of ballistic and direct-energy weapons. Better CIWS, better SAMs, and better tactical high-energy lasers than the THEL/MTHEL. Ask the Russians for joint-development for next-generation S-300/S-400 platform.
3) Develop and mass produce cruise missile capability, as well as delivery & guidance capability. This could be a combination of mass-production DH-10 and domestic GPS satellites. The cruise missile should be a "common platform" that can be used for anti-surface, anti-ship, and even nuclear warhead option. These "Chinese Tomahawks" should be produced by the thousands.
The PLA, PLAAF, and PLAN should all have delivery platforms, ranging from bombers to SSG/SSGN's. The US Ohio-class SSGN is a good model. The PLAN can builder smaller versions, carrying 64-96 LACM's each.
4) Pay $$ for joint-development with Russia and India for conventional weapons. Areas to concentrate on: PAK-FA, ASW (sonar and weapons), S-400, missile technology. 3 wallets is better than one. The PLAAF still has some to learn from the Russians, and the PLAN really needs better ASW weapons.
5) Fund UAV development. Armed and unarmed UAV's for the sky and under-water. The Israeli Harpy is a good concept.
The future battlefield - rather than tanks getting into shooting range, your trucks deploy Harpy-like UAV's with 500+ km range. A line of trucks launch dozens of attack UAV's, which flies toward the enemy armed column and perform saturated attack from the air. By the time that your tanks arrive, the enemy armor is a smoking heap.
===============
None of the above suggest rapid expansion of the PLA at this time. The PRC is in a good position today where it's not in danger of being invaded, and military conflicts would only occur by PRC's choosing 98% of the time (excluding Mr. Kim in North Korea). There is no need to expand the PLA by the millions. All 3 branches can be given funding for gradual upgrade of equipment, but more funding should be allocated to R&D areas specified above.
As for the PLAN, I'd say give them new ships, but at the same time demand them to retire and transfer older naval assets to a new unified coast guard service. Ships transferred to the coast guard should have its SSM's removed, and be equipped with modern CIWS and helicopter deck. Each of the 3 fleets's surface fleet should be given 8 DDG, 8 FFG, plus a few ships in reserve. In addition, the Navy should organize rapid reaction group cenetred around LHD's, and organize separate littoral combat group with smaller ships. Such a navy is conservative in size, affordable, and should not look overly threatening to PRC's neighbors.
